Question

Check and discuss the above relations in the case of angles between 0º and 90º,

whether they hold for these angles or not?

So, sin (90o − A) = cos A cos (90o − A) = sin A

tan (90o − A) = cot A and cot (90o − A) = tan A

sec (90o − A) = cosec A cosec (90o − A) = sec A
solutions. ​

Answer 1

Step-by-step explanation:

Check and discuss the above relations in the case of angles between 0º and 90º,

whether they hold for these angles or not?

So, sin (90o − A) = cos A cos (90o − A) = sin A

tan (90o − A) = cot A and cot (90o − A) = tan A

sec (90o − A) = cosec A cosec (90o − A) = sec A

solutions.
