Question

OR
If sin=
1/2 and cose
then find the value cote.​

Answer 1

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.
