Q. If

A = 30^{0}

, then

s i n 3 A = 3 sin A - 4 {sin}^{3} A

If true enter 1 else 0

s i n 3 A = 3 s i n A - 4 s i n^{3} A

If true then write 1 and if false then write 0

Q. If

sec A = \frac{5}{4}

, verify that

\frac{3 sin A - 4 {sin}^{3} A}{4 {cos}^{3} A - 3 cos A} = \frac{3 tan A - {tan}^{3} A}{1 - 3 {tan}^{2} A}

If sec $A = \frac{5}{4}$ , verify that $\frac{3 s i n A - 4 s i n^{3} A}{4 c o s^{3} A - 3 c o s A} = \frac{3 t a n A - t a n^{3} A}{1 - 3 t a n^{2} A}$
