Question

if cos A =5/13 verify that (3sin A- 4 sin^3 A)/(4 cos^3 A - 3 cos A) = (3 tan A - tan^3 A)/ (1- 3 tan^2 A)

Answer 1

Answer:

if cos A =5/13 verify that (3sin A- 4 sin^3 A)/(4 cos^3 A - 3 cos A) = (3 tan A - tan^3 A)/ (1- 3 tan^2 A)

Answer 2

Step-by-step explanation:

if cos A =5/13 verify that (3sin A- 4 sin^3 A)/(4 cos^3 A - 3 cos A) = (3 tan A - tan^3 A)/ (1- 3 tan^2 A)if cos A =5/13 verify that (3sin A- 4 sin^3 A)/(4 cos^3 A - 3 cos A) = (3 tan A - tan^3 A)/ (1- 3 tan^2 A)if cos A =5/13 verify that (3sin A- 4 sin^3 A)/(4 cos^3 A - 3 cos A) = (3 tan A - tan^3 A)/ (1- 3 tan^2 A)
