Use the value of the trigonometric function to evaluate the indicated function. Sin(t) = 4/5 Find sin(t). Recall that the sine, cosecant, tangent and cotangent functions are odd. In other words, Sin(t) = sin(t) csc(t) = csc(t) tan(t) = tan(t) cot(-t) = cot(t). Also recall that the cosine and the secant functions are even. In other words, cos(t) = cos(t) sec(t) = sec(t).
