Differentiation of cos(x-y)
Answers
Answer:
-sin (a)
Step-by-step explanation:
This is 'CHAIN RULE.'
To solve this question we need to know that to whose respect we are differentiating. But, here i am differentiating with respect to x. So,
so now differentiate 'cos a' we get,
as we now that actually we are differentiating cos
(x-y) and not cos (a) so we will differentiate (x-y) using difference rule.
as differentiation of y will be 0 as we are differentiating with respect to x so Final Answer = 1 X - sin (a)
= - sin (a)
Question:
Differentiation of cos(x-y)
Solution:
The differentiation of cos(x-y) is [-sin(x - y)]
Explanation:
We have applied chain rule along with differentiation rule of
[cos(u(x))]' = - sin(u(x)) * u'(x)
The sign [ ' ] here means single time differentiation.
As there are more signs number of differentiation times increases.
