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 (90^(@)-A) = cos A" "cos (90^(@)-A) = sin A`
`tan (90^(@)-A) = cot A" "cot (90^(@)-A) = tan A`
`sec (90^(@)-A) = cosec A and " "cosec (90^(@) -A) = sec A`

Check and discuss the above relations in the case of angles between 0° and 90° , whether they hold for these angles or not? cosec (90^@- A) = sec A

Check and discuss the above relations in the case of angles between 0^@ and 90^@ , whether they hold for these angles or not? Sin (90^@- A) = cos A
