Question

tan/1 - cot + cot/1+tan​

Answer 1

Answer:

0

Step-by-step explanation:

tan/1 - 1/tan + cot/1 + 1/cot (since tan = 1/cot)

tan square - 1/tan + cot square + 1 ( by taking LCM )

tan square*cot-cot+cot square*tan-tan/tan*cot

tan square*1/tan-cot+cot square*1/cot-tan

cancel tan and tan on denominator and cot similarly

then

tan-cot+cot-tan/tan*cot

0/tan*cot

=0
