The function y = (3x2+2x+5)10 is an example of a "function within a function", which means the thing in the brackets is a function itself, and it's being raised to the powe...
Log base 10log(x)=4 ~ 104 =xx=10000
x = -1/3 and y = 1/3 or x = -1/7 and y = -3/7
We know that tan x = sin x/cos x and so tan2x = sin2x/cos2x. We also know that sin2x + cos2x = 1 because this is a Pythagorean identity. We can rewri...
When we integrate, we raise the power by one and divide the term by the new power. So let's break the question down term by term. When integrating 2x2 we raise the power by 1 to get 2x3EFAnswered by Eleanor F. • Maths tutor4603 Views
