Question

write the simplest form of the product
sin A . cot A/sec A​

Answer 1

Answer:

solution

Step-by-step explanation:

SinA. CotA/SecA

SinA. CosA/SinA×CosA....... (CotA=Cos/Sin, SecA=1/Cos

Cos^2A

Answer 2

$\huge\mathrm{\red{Solution}}$

LETS TAKE A LOOK AT THE CONVERSIONS FIRST -

Cot A = $\dfrac{Cos A}{Sin A}$

Sec A = $\dfrac{1}{Cos A}$

NOW,

Correct codes:

$\sin(a).\dfrac{\cot(a)}{\sec(a)}$

$\sin(a).\dfrac{\dfrac{\cos(a)}{\sin(a)}}{\dfrac{1}{\cos(a)}}$

$\sin(a).\:\dfrac{\cos(a)}{\sin(a)}\times\:\dfrac{ </p><p>\cos(a)}{1}$

$\cancel{\dfrac{\sin(a)}{\sin(a)}}\times\cos(a)\times\cos(a)$

$\huge{\red{\underline{{Cos}^{2}(a)}}}$
