Question

ae or more than one correct answer type questions: If \( \sec A=\frac{5}{4} \), then a) \( \sec ^{2} A-\tan ^{2} A=1 \) b) \( 5(\cos A-\sin A)=7 \) c) \( 5(\cos A+\sin A)=7 \) d) \( \cot ^{2} A -\operatorname{cosec}^{2} A =1 \)

Answer 1

piyush0681, hello

If secA = 5/4, then both a) and c) are also correct.
