WebFeb 1, 2024 · To determine the sine of an angle given its cosine and tangent, you need to multiply cosine by tangent. The formula you need is: The formula you need is: sin(α) = … Webwe discuss the four other trigonometric functions: tangent, cotangent, secant, and cosecant. Each of these functions are derived in some way from sine and cosine. The tangent of x is defined to be its sine divided by its cosine: tanx = sinx cosx: The cotangent of x is defined to be the cosine of x divided by the sine of x: cotx = cosx sinx:
Webcosecant, secant and tangent are the reciprocals of sine, cosine and tangent. sin-1, cos-1 & tan-1 are the inverse, NOT the reciprocal. That means sin-1 or inverse sine is the … WebExpress each trigonometric ratio in terms of sin(x) and cos(x) sm x cos x 1 + cot(x) CSC x cœ(z) ...
