Answer:
Step-by-step explanation:
∫cos(x+b+a-b)/sin(x+b)dx
cos(a-b)∫cot(x+b)dx -sin(a-b)∫1dx
cos(a-b)log|sin(x+b)|-xsin(a-b)+c

how ∫cos(x+a+a-b) that a-b came ?? any rules ?? formula ??
no there is no such rule
but that's the trick used for sums with trigo functions in both denominator and numerator
hope you understood
nope still but i will try to understand by focusing in logic Thanks anyways // my basic is weak and I m trying to Mastering integration 14 to 15 hour day only Integration making lol ✅
