How do you solve trigonometry problems in class 11?
Basic Trigonometric Formulas for Class 11
- cos (A + B) = cos A cos B – sin A sin B.
- cos (A – B) = cos A cos B + sin A sin B.
- sin (A+B) = sin A cos B + cos A sin B.
- sin (A -B) = sin A cos B – cos A sin B.

How can I study trigonometry?
How can you study Trigo. Make class note neat and clean. When it come to formula then try to remember formula with number. Trigonometry is one of interesting topic of mathematics. It require highly critical multidimensional thinking,quick recalling of formula’s. In trigonometry one question can be done is several ways (Mostly proof).
Does the trigonometry proving miracle really happen?
More often than not, the miracle does not happen. This is because most proving questions revolve majorly around good old expansion, factorization, simplification and cancelling of like terms. In fact, some proving questions do not even require student to use any trigonometry rules at all.
