Question

prove to that 1 + tan square theta upon cos square theta is equal to tan square theta ​

Answer 1

Answer:

Step-by-step explanation:your questionust be wrong it would be cot instead of cos for this

Answer 2

LHS = tan²A - sin²A

= ( sin²A/cos²A ) - sin²A

= sin²A [ 1/cos²A - 1 ]

= sin²A( sec²A - 1 )

= sin²A tan²A

[ since , sec²A - 1 = tan²A ]

= tan²Asin²A

= RHS
