I'm in an algebra based calculus class. He doesn't want us using calculus. That's probably why we weren't taught the derivative part.

Okay! I forgot to multiply all of the numbers by 2! I'll do that now. Thank you so much for your help! You don't even understand how much it means to me!

I solved using theta values = 0, 10, 20, and so on. It increased from R=0 to R=91.83 at theta=90. This was the highest value, but am I doing something wrong? If you shoot an object straight into the air, shouldn't it come straight down?

R(θ) = Vo2 sin(2θ)/g R = (30^2 * sin(21))/9.8 = 32.91 m

No and I've read the chapter in my physics book twice, but still don't understand

We are given the velocity at which an object is projected (30 m/s) at an angle theta. I have to "Plot the range R as a function of angle theta (a value somewhere between 0 and 90 (including 0 and 90)). My thought was to possibly determine R using theta = 0 and theta = 90 to find a range, but...
