One notable relationship between the sine and cosine functions is that, suppose we have cos. ⁡. ( θ), a phase shift of 90 ∘ of the angle θ would give an equivalent sine value. Showing this mathematically, cos. ⁡. ( θ + 90 ∘) = sin. ⁡.

How do you find the trigonometric functions of any angle? Well, I guess you could use a special representation of the function through a sum of terms, also known as Taylor Series. It is, basically, what happens in your pocket calculator when you evaluate, for example, #sin (30°)#. Your calculator does this: #sin (theta)=theta-theta^3/ (3 ...In trigonometry we use the functions of angles like sin, cos and tan. It turns out that angles that have the same reference angles always have the same trig function values (the sign may vary). So for example sin(45) = 0.707. The angle 135° has a reference angle of 45°, so its sin will be the same. Checking on a calculator: sin(135) = 0.707
