Evaluate the trigonometric function of given below where is

Evaluate the trigonometric function of given below, where is an acute angle determined by an inverse trigonometric function. (Hint: Make a sketch of a right triangle containing angle .) tan , if =sin^1 19x

Solution

sin = 19x

perpandicular = 19x, hypotenuse = 1, base = sqrt(1 - 361x^2)

tan = 19x/sqrt(1 - 361x^2)
