This a relatively simple question which requires the use of the chain rule to solve. First we set u = sin(x) so we then have y = u2 . Next we perform do differentiations, one on u as a functio...
To solve this problem, you need to: rearrange the first equation (1) to express y in terms of x to obtain equation (3). Then, substitute this new equation into the quadratic one (the second equation from ...
Using trig formulas we have sin(5x+3x)= sin(5x)cos(3x)+cos(5x)sin(3x) and sin(5x-3x)= sin(5x)cos(3x) - cos(5x)sin(3x). Hence, sin(5x+3x) - sin(5x-3x) = sin(8x)-sin(2x) = 2cos(5x)sin(3x). This implies that...
ln((4^x)e^(7x+5)) = ln21; apply a natural log on both sides of the equation as an exponential containing e is involved
ln4^x + ln(e^(7x+5)) = ln21; using logarithm rules you can seperate the singl...
First we should look at the formula for integrating xn. The integral is (xn+1 / n+1) + C.
Let's break down our equation into two parts.
