Question

tan (90°-A). cot A
Sec (90°- A) - cosec A​

Answer 1

Step-by-step explanation:

this is a formula for solving questions on trigonometric ratios of complementary angles

the above two formulas are absolutely correct

other formulas are

sin(90-A)=cos A

cos(90-A)=sin A

tan(90-A)=cot A

cot(90-A)=tan A

sec(90-A)=cosec A

cosec(90-A)=sec A

Answer 2

Answer:

sin {90°-A} -cos A √√π×~|∆•
