Using the general rule d/dx(a*x^n) = a *n * x^(n-1) and the linearity of the derivative operator, we obtain:
6x^5+20x^3+0 = 6x^5+20x^3

Draw a diagram of the graph y=sin x between the stated interval. Identify the two extrema. Required interval is in between the two points.

y= ln(4x-7)+18 y= a(x^2 +b)^1/2
At x=2 dy/dx = dy/dx and y =y
At x =2 y = ln(8-7) +18 y = ln 1 +18 y =18
At x = 2 18=a(4 +b)^1/2 18/(4+b)^1/2= a
y=ln(4x-7)+18dy/dx= 4/(4x...

a) Integrate the given expression using integration laws we have learnt to give [(x^4)/4 + (3(x^2))/2 + 2x ] and you do not need a +c constant as we have limits.b) Substitute the limits into the equation ...

Firstly rearrange the quadratic such that the coefficient of x² is positive (already done in this example) and the quadratic is in the form of ax² +bx + c, then solve for ...
