Point slope: y-y1 = m(x-x1)
Plug in the numbers
Solution: y+2 = -4(x + 9)
Answer:
2x(sinx^2 + x^2cosx^2).
Step-by-step explanation:
We use the product rule:
If u and v are functions of x then:-
d(uv)/dx = u dv/dx + v du/dx
So:
d(x^2 sinx^2)dx
= x^2 * d(sinx^2)/dx + sinx^2 * d(x^2)/dx
= x^2 * 2xcosx^2 + sinx^2 * 2x
= 2x^3cosx^2 + 2xsinx^2
= 2x(sinx^2 + x^2cosx^2).
8x^2 - 50 =
2(4x^2 - 25) =
2(2x + 5)(2x - 5) <==
