Question

5 tan square A-5sec square A =

Answer 1

Answer:

-5 will be the answer

Step-by-step explanation:

A/q 5tan²a-5sec²a= take common as 5 then it will be =5(tan²a-sec²a) and we know that sec²a- tan²a=1 that is trigonometric formula so reverse tan²a - sec²a =-1 so apply it in the equation we get 5(-1) =-5 hence proved
