Cos Sin. Sine of angle is equal to the ratio of opposite side and hypotenuse whereas cosine of an angle is equal to ratio of adjacent side and hypotenuse. The value of sin 1 cos 2 cos 1 sin 2 tan 1 cot 4 cot 1 tan 4 sec 1 csc 6 csc 1 sec 6 View solution.
For math science nutrition history geography engineering mathematics linguistics sports finance music WolframAlpha brings expert-level knowledge and capabilities to the broadest possible range of. In other words sinθ is the opposite side divided by the hypotenuse. The sum of the cosine and sine of the same angle x is given by.
42 We can write cos x as sin π2x so the left-hand side of Equation 42.
We note that sin π4cos π412 and re-use cos θsin π2θ to obtain the required formula. Cos cos-1sqrt 1- 56652 because sin-1xcos-1sqrt 1-x2 cos cos-1 3365 3365 Concept. Hope it will be helpful to you.
