Sin 45 degrees exact value

If u know value of sin30 and sin45 u can easily calculate sin40 Value of sin30=.5 and sin45=.70 U can asume value of sin40 is .64 becauese sin45>sin40 and sin30 <;sin40 Find the exact value of sin 90 degrees using the functions of 45 degrees. - Answered by a verified Tutor The trivial values. In degree format, sin and cos of 0, 30, 45, 60, and 90 can be calculated from their right angled triangles, using the Pythagorean theorem. In radian format, sin and cos of π / 2 n can be expressed in radical format by recursively applying the following: Learn the value of sin 60 degrees along with other degree values like 0, 30, 45, 90, 180, 270 and 360 (degrees). Also, know the values of cosine and tangent ratios. 2007-11-17 · How do you find the exact value of sin 15 degrees? Answer Save.

sin(45 degrees) = 1 / √(2) We can see that whether we use the right triangle only or the unit circle, we get the same answer. Since trigonometry means the measurement of triangles, you may have wondered so far why we use the unit circle to do trigonometry.
