Answer 1

Step-by-step explanation:

3sin^2x + 3/sec^2x3sin^2x + 3/sec^2x

Answer 2

Answer:

3

Step-by-step explanation:

$3 \sin^{2}x + \frac{3}{ \sec^{2} x } \\ = 3 \sin ^{2} (x) + 3 \cos^{2} (x) \: ( since \: \sec x = \frac{1}{ \cos x} ) \\ = 3( { \sin}^{2} x + { \cos}^{2}x) \\ = 3(1) \: (since \: { \sin }^{2}x + { \cos }^{2} x = 1 ) \\ = 3$
