Question

\(\frac {Cos A}{Sin A}\) = ______

(a) Tan A

(b) Sin A

(c) Cot A

(d) Sec A

The question was posed to me in final exam.

Asked question is from Trigonometric Ratios topic in division Trigonometry of Mathematics – Class 10

Answer 1

Right option is (c) Cot A

For explanation I would say: Sin A = \(\frac {Length \, of \, the \, opposite \, side}{Length \, of \, the \, hypotenuse}\), Cos A = \(\frac {Length \, of \, the \, adjacent \, side}{Length \, of \, the \, hypotenuse}\)

\(\frac {Cos A}{Sin A} = \frac {Length \, of \, the \, adjacent \, side}{Length \, of \, the \, opposite \, side}\)

= Cot A
