Question

Please differentiate
y = cos x - sin x / cos x + sin x
Please answer with steps .​

Answer 1

Answer:

hope you understand

Step-by-step explanation:

dy/dx= -sin x- {cos x d (sin x) /dx- sin x d(cos x)}/ cos^2 x+ cos x

         =- -sin x-(cos^2 x+ sin ^2 x)+ cos x

         = cos x - sin x  [cos ^2 x+ sin^2 x =1]

Answer 2

Step-by-step explanation:

Derivation

Resistance (R) = Voltage × Current-1 . . . . (1)

Since, voltage (V) = Electric Field × Distance = [Force × Charge-1] ×
