Question 12:
It seems hard to 'show' because it just is, is there any other steps to make it look like I was 'showing'?
Question 13: Find the area bounded by the curve y = x^4 + 1, the y-axis and the lines y = 1 and y = 3 in the first quadrant, correct to 2 significant figures.
d/dx 3^3x+1 dx
= (3^3x+2) * ln 3
= 3^3x+2.ln3
= (3^3x+2) * ln 3
= 3^3x+2.ln3
