Answer 1

Write the differential coefficient of the following :

1. d(sin x)/dx

= d(sin)d(x)/dx

= (dsin)(dx)/dx

= dsin

2. d(sec x)/dx

= d(sec)d(x)/dx

= (dsec)(dx)/dx

= dsec

3. d(cot x)/dx

= d(cot)d(x)/dx

= (dcot)(dx)/dx

= dcot

Answer 2

Answer:

Write the differential coefficient of the following :

1. d(sin x)/dx

= d(sin)d(x)/dx

= (dsin)(dx)/dx

= dsin

2. d(sec x)/dx

= d(sec)d(x)/dx

= (dsec)(dx)/dx

= dsec

3. d(cot x)/dx

= d(cot)d(x)/dx

= (dcot)(dx)/dx

= dcot
