Values of Trigonometric ratios for 0, 30,45, 60 and 90 degrees. I have noticed that students cannot actually remember values of six trigonometric ratios (sin, cos, tan, cosec, sec and cot) for 0, 30, 45, 60 and 90.These values are used very often and it is recommended from my point of view that student should be able to tell the values instantly when asked.
23 Aug 2012 Values of Trigonometric ratios for 0, 30, 45, 60 and 90 degrees. August 23 Hence, all the tan values can be obtained from sin and cos values. tan 0 = sin 0 The values for 360 are the same exact values for 0. Sin 0
and cos30∘ = √3 2. Note we cannot have cos30∘ as − √3 2, as cosine of an angle in Q1 cannot be negative. Answer link. 30 → sin (30°) = 0.5. pi → sin (pi rad) = 0. 3pi/4 → sin (3pi/4) = 0.707 1/ (2pi) → sin (1/ (2pi) rad) = 0.158 (note the parenthesis in denominator) 1/2pi → sin (1/2pi rad) = sin ( (1/2) x pi rad) = 1 exactly. Note: this calculator accepts numbers, fractions, 'pi', 'π', '+', '-', '*', '/', ' (', ')' and some (not all) combinations of them as input.

If the angle of a right triangle is equal to 30 degrees, and then the value of cosine at this angle i.e., the value of Cos 30 degree is in a fraction form as √3/2. $\cos{(30^°)} \,=\, \dfrac{\sqrt{3}}{2}$ The value of cos of angle $30$ degrees is equal to $\dfrac{\sqrt{3}}{2}$ in fraction form exactly. It is an irrational number and equals to $0.8660254037\ldots$ in decimal form and the same value is considered as $0.866$ approximately in mathematics. The value of cos $30^°$ is usually called as The exact value of cos(30°) is √(3) / 2.
The value of cos $30^°$ is usually called as Find an answer to your question What is the exact value of cos 30 degrees ellyrenae ellyrenae 03/25/2020 Mathematics Middle School answered What is the exact value of cos 30 degrees 1 See answer ellyrenae is waiting for your help. Add your answer and earn points. sin30^0 = 1/2, cos 30^0 = (sqrt 3) /2 and tan 30^0 = 1 / sqrt 3 Now csc 30^0= 2,sec 30^0 = 2/sqrt 3 and cot 30^0 = sqrt3.
30 → sin (30°) = 0.5. pi → sin (pi rad) = 0. 3pi/4 → sin (3pi/4) = 0.707 1/ (2pi) → sin (1/ (2pi) rad) = 0.158 (note the parenthesis in denominator) 1/2pi → sin (1/2pi rad) = sin ( (1/2) x pi rad) = 1 exactly.

Sun (A- sin(90+30) is in the form of sin (A+B) sin(A+B)= sinA cosB+CosA sinB sin(90+30) =sin90 cos30 What is the value of exact value of cos 8π/3=? which it is not true when you use radians but it is a true statement when you are using deg Use \cos A=\cos 30^{\circ}=\frac{\sqrt{3}}{2} to show that the exact value of \tan In mathematics, the absolute value or modulus |x| of a real number x is its numerical Um, with the 30 degrees and stinks, that angle is 30 degrees, Find the Exact Value cot(330 degrees ) Apply the reference angleby finding Re : Values for sec, tan, cot cos 330 degrees is 30 degrees less than 360 degrees. For this reason, it is helpful to have the values of sine, cosine, tangent, and Example 1: In the above Table, left column, it is found that cos30 = √3/2.
Notice, [math]\cos^{2}30^\circ=(\cos30^\circ)^2=(\sqrt3/2)^2=\frac34 [/math]
And then, the exact value of cos 30 degrees is written as 0.8660 approx. √3/2 is the value of Cos 30° which is a trigonometric function of a particular angle. The value of cos of angle 30 degrees is equal to √32 in fraction form exactly. It is an irrational number and equals to 0.8660254037… in decimal form and the same value is considered as 0.866 approximately in mathematics.
The result can be shown in multiple forms.

The exact value of cos(30°) is √(3) / 2. We can find this using the cosine half-angle identity property which is as follows: If an angle, See full answer below.
Answer link. 30 → sin (30°) = 0.5.
cos 30° = sin 60° = √3/2 cos 45° = sin 45° = 1/√2 cos 60° = sin 30° = 1/2 cos 90° = sin 0° = 0 So, for cos, it will be like 1, √3/2, 1/√2, 1/2, 0 For tan We know that tan θ = sin θ /cos θ So, it will be tan 0° = sin 0° / cos 0° = 0/1 = 0 tan 30° = sin 30° / cos 30° = (1/2)/ (√3/2) = 1/√3 cos(30°) = [ 0; 1, 6, 2, 6 ] cos 2 (30°) = [0; 1, 3] tan(30°) = [ 0; 1, 1, 2 ] tan 2 (30°) = [0; 3 ] π 5: 36 `color{blue}{(sqrt 5 + 1)/4 = sqrt((3+sqrt 5)/8)}` `color{blue}{sqrt(5 - 2 sqrt 5)}` 54: 3 π 10: cos(36°) = [ 0; 1, 4 ] cos 2 (36°) = [ 0; 1, 1, 1, 8, 2 ] tan 2 (36°) = [ 0; 1, 1, 8, 2 ] 5 π 24: 37.5 `color{blue}{sqrt(2 + sqrt( 2 - sqrt 3))/2 }` The value of tangent of angle 30 degrees can also be evaluated using the values of sin 30 degrees and cos 30 degrees.
