Answer:
a. ∫ xSinx dx
iii. integration by parts
u =x and dv= sinx
b. ∫ x⁴/(1+x³). dx
ii. neither
Long division is an option here before integration is done
c. ∫ x⁴. e^x³. dx
i. substitution
where u = x⁵
d. ∫x⁴ cos(x⁵). dx
i. substitution
where u = x⁵
e. ∫1/√9x+1 .dx
i. substitution
where u = 9x+1
Step-by-step explanation:
Difference of Squares: a² - b² = (a + b)(a - b)
(x² - 16) / (x - 4)
= [(x + 4)(x - 4)] / (x - 4)
= x + 4, where x =/= 4.

Step-by-step explanation:
angle 1 & angle 2 are linear pair. That means both the angles form a straight angle (or 180°). Hence ,


Also it's given that angle 1 & angle 3 are supplementary. It means that their sum will be equal to 180° . So ,

Putting the value of m(1) in above eqn. gives :-





Simple...
you have:



We can immediately see this is false.
Thus, your answer.
