Question

If sec theetah - tan theetah =4, then prove that cosec theetah = 8/17

Answer 1

sec theetah - tan theetah =4 Sec@=4+tan@ Squaring both side Sec2@=16+tan2@+2tan@ 1+tan2@=16+tan2@+2tan@ 16+tan2@+2tan@-1-tan2@=0 15-2tan@=0 15=2tan@ I think yr questions is wrong because hypothesis is always greater then perpendicular and Base
