17 tan3 in terms with no power greater than 1 If the ball tr

If the ball travels 242 feet, what is theta to the nearest degree? Use a double-angle identity to rewrite the equation for d. Rewrite each expression in terms with no power greater than 1. Cos^3 theta tan^3 theta sec^4 theta cot^3 theta cos^4 theta-sin^4 theta sin^2 theta cos^3 theta sin^2 theta-cos^2 theta sin^4 theta/cos^2 theta

Solution

tan³

=tan*(tan)²

=tan*(sin/cos)²

=tan*(sin²/cos²)

sin² =(1-cos2)/2 ,cos² =(1+cos2)/2

=tan*((1-cos2)/2 )/((1+cos2)/2 )

=tan*(1-cos2)/(1+cos2)
