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

answer: the area of the parallelogram below is 42 square meters.

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
