WebTrigonometric ratios of 90 degree plus theta is a part of ASTC formula in trigonometry. Trigonometric ratios of 90 degree plus theta are given below. sin (90° + θ) = cos θ. cos (90° + θ) = - sin θ. tan (90° + θ) = - cot θ. csc … WebSo if you start at 0 degrees, you are to the right, so cosine is one and sine is zero. If you increase the angle, the cosine will start decreasing slowly (as you are moving slowly leftward) while the sine is increasing (as you move up). You reach the top at 90 degrees. Since the circle is symmetric, increasing.
