Question

What does integration using trigonometric identities mean?

Options

• Converting a trigonometric expression into an easier form with the help of standard identities before integrating.

• Integrating every trigonometric expression directly without simplification.

• Replacing every trigonometric function with an algebraic variable.

• Differentiating a trigonometric expression before applying any identity.

Answer 1

Integration using trigonometric identities involves simplifying the trigonometric expression first. Standard identities are used to obtain an easier form before integration.
