Question

1-tan sqA/cot sqA-1=tan sq A​

Answer 1

Answer:All values of A except (2n+1)pi/4 where n is any integer

Step-by-step explanation:1-tan sqA/cot sqA -1= i- tan sqA/ (1/tan sqA)-1=tan sqA* [1 - tan sqA/1 - tan sqA]= RHS= tan sqA

therefore tan sqA gets cancelled and also the nr and dr. therefore its always true except at places where cot sqA is 1, where the dr is 0 and thus the lhs is not defined.
