Question

if cotA=1, then the value of 1+cosA / sinA​

Answer 1

Answer:

2

Step-by-step explanation:

Given cot A =1

cot A= 1/ tanA = cos A/ sin A

The value of 1+ cosA/sinA will be 1+1=2 .

Answer 2

$\huge{\mathcal{\underline{\green{SOLUTION}}}}$

$cotA=1$

$\displaystyle\implies \: A \: = {45}^{°}$

$\frac{1 + cosA}{sinA} = \frac{1 + cos{45}^{°}}{sin{45}^{°}} \: = \frac{1 + \frac{1}{ \sqrt{2} } }{ \frac{1}{ \sqrt{2} } } = \sqrt{2} + 1$
