Find dy/dx given that y = sin x / 1 + cos x​

Step-by-step explanation:

differentiating numerator wrt x :-

(sinx)' = cos x

differentiating denominator wrt x :-

(1 + cos x)' = (cosx)' = - sinx

here,

since cos²x + sin²x = 1

diving numerator and denominator by 1 + cos x

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
