Question

(tan²θ + 1) + (cot²θ + 1)=

Answer 1

Answer:

(sin /cos)ka whole sqare

Answer 2

Answer:

tan²theta +1 = sec²theta

and cot²theta +1 = cosec²theta

put them in above question

we get

sec²theta + cosec²theta

1/cos²theta + 1/sin²theta

(sin²theta + cos ²theta)/sin²theta.cos²theta

1/sin²theta.cos²theta...

hope this will help you
