Question

if tanA=3/4 ,then the value of 4sin^2A- 2cos^2A/4sin^2A+3cos^2A is equal to?

Answer 1

Answer:

Step-by-step explanation:

Tan A = Sin A/Cos A

          =3/4

Means that sin A = 3.

&,

                   cos A = 4.

so,

4sin^2A- 2cos^2A/4sin^2A+3cos^2A =>=>

              4*(3)^2 - 2*(4)^2/4*(3)^2 + 3*(4)^2

              36 - 32/36 + 48

              36 - 8/9 + 48

              36*9 - 8 + 48*9/9

              324 - 8 + 432/9

              316 + 432/9

              748/9
