Cos theta 43 find cot thetaSolutioncostheta 45 so first co

Cos theta = 4/3, find cot theta

cos(theta) = 4/5

so first

cot(theta) = cos(theta) /sin(theta)

we have to find sin(theta) value

identity sin^2(theta) +cos^2(theta) =1

sin^2(theta) + (4/5)^2 =1

sin^2(theta) = 1 - 16/25

sin^2(theta) = 9/25

sin(theta) = 3/5

so cot(theta) = [4/5] /[3/5]

= 4/3
