Question

if sin A =1/2, then what is the value of cot A​

Answer 1

Answer:

CotA=$\sqrt{3}$

Step-by-step explanation:

sin A = 1/2

we know that sin²A + cos²A = 1

so

cos²A= 1 - (1/2)²

cos²A= 1 - 1/4

cos²A = 3/4

cosA= √3/√4

cosA= √3/2

Now, cotA = cosA/ sinA

So, CotA= $\frac{\frac{\sqrt{3} }{2} }{\frac{1}{2} } \\= \sqrt{3}$

Thus, CotA= square root 3

Answer 2

hey mate

given here

sinA= 1/2.

find here

cot A=?

we know that ,

cotX=√{1-sin²x}

so,

cos A=√{1-sin ²A}

=√{1-(1/2)²}

=√{1- 1/4}

=√[{4-1}/4]

=√(3/4)

=(√3)/2

then,

cotA= cos A /sin A

=[{(√3)/2}/(1/2)]

=[(√3)/2 × 2]

= √3.

i hopes its helps u.
