Question

solve this fast this is important don't copy paste handwritten pls pls pls​

Answer 1

Steps of doing

• Simplify LHS and RHS seperately
• Then form LHS in the form of cosA and sinA
• take LCM and reciprocal it and cut sinA with sinA
• Then take common cosA from both numerator and denominator
• cut cosA and simplify then you will find LHS is equal to RHS
• Hence it is proved

Note

1. In trigonometry you have to simplify LHS and RHS seperately
2. Observe LHS first you will find similarities between LHS and RHS
