if int e^(2x)sin x cos xdx=(u)/(8)e^(2x)+c then u

Find the zeroes of the following quadratic polynomials and verify the relationship between the zeroes and the coefficients. - (i) x^2-2x-8 (ii) 4s^2-4s+1 (iii) 6x^2-3-7x (iv) 4u^2+8u (v) t^2-15 (vi) 3x^2-x-4

Find the zeroes of the following quadratic polynomials and verify the relationship between the zeroes and the coefficients. - (i) x^2-2x-8 (ii) 4s^2-4s+1 (iii) 6x^2-3-7x (iv) 4u^2+8u (v)t^2-15 (vi) 3x^2-x-4

Identify the following as monomial binomial or trinomial expressions: (i) 7u^(6) (ii) y^(2)-2y+6 (iii) x^(2) (iv) x^(6)-sqrt(3)x (v) x^(3)-3x+2 (vi) u^(2)+2u

If u = x ^ (4), show that (y ^ (3) u) / (y x ^ (2)) = (^ (3) u) / (x and x)

If (x+yi)^(3)=u + vi , prove that (u)/(x) +(v)/(y) = 4(x^(2)-y^(2))

If (x+iy)^(3)= u +iv , then show that (u)/(x)+(v)/(y)=4(x^(2)-y^(2)) .

Given y=f(u) and u=g(x) Find (dy)/(dx) if y=2u^(3),u=8x-1
