Answered by maham237 @
Sin Θ = opposite / hypotenuse
cos Θ = adjacent / hypotenuse
tan Θ = opposite / adjacent
sin x = 1/2 ⇒⇒ opposite is 1 ; hypotenuse is 2
cos x = ? / 2 ⇒ ? = √3 value of adjacent
tan x = 1 / ?

Implicit differentiation: ycosx=x^2+y^2
Derivative of both sides:
=((y)(-sinx)+(cosx)(dy/dx)=2x+2y(dy/dx)
=(-ysinx+cosx(dy/dx)=2x+2y(dy/dx)
=cosx(dy/dx) - 2y(dy/dx) = ysinx+2x
=(cosx-2y)dy/dx = ysinx+2x
=dy/dx = (ysinx+2x)/(cosx-2y)
