Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;)

Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!”

You are better than all of the tutors of UH Central combined and I am not exaggerating

yes, as long as that constant was multiplied by the initial equation. :)

if they don't give bounds then you can use 0 to 2pi. :)

you forgot to mention that it just so happens that the part of the graph youre looking at is all above the x-axis, but if we are looking at the entire polar curve then after taking the square root we need an absolute value sign on the sin(theta/2)

If there were a constant a in the initial equation, the final answer would just be multiplied by a factor of a correct?
