Question

integration of sin (5 - 7 x) dx​

Answer 1

Answer:

x /2 ( 10 - 7x^2)

Explanation

integration of 5 dn is. 5x

,, ,, - 7xdx is 7x^2 /2

on solving we get answer

Answer 2

Answer:

$\frac{\cos(5 - 7x) }{7} + c$

Step-by-step explanation:

$\text { Let, } I=\int \sin (5-7 x) d x \\</p><p>\text { put } 5-7 x=t \\</p><p>-7 dx =d t \\</p><p>d x =\frac{d t}{7} \\</p><p>I =\int \frac{\sin t}{-7} d t \\</p><p>I =-\frac{\cos t}{-7}+c \\</p><p>I =\frac{\cos t}{7}+c</p><p>$
