Question

prove that (1+cot theta-cosec theta)(1+tan theta +sec theta)=2 ​

Answer 1

Step-by-step explanation:

here is your ans....

.......

Answer 2

(1+ cot - cosec) ( 1+ tan + sec)

( 1+ cos/sin - 1/sin)( 1+ sin/cos +1/cos)

sin + cos -1) ( sin + cos +1)/ sin cos

( sin+ cos)^2 -1)/ sin cos

sin^2 + cos^2 + 2 sincos-1)/sin cos

1+ 2 sin cos -1)/ sin cos

2 sin cos/sin cos
