Human error on my behalf. I mistype it. But yeah, thank you. I'm self-teaching (as scary enough as it is, ha ha) so no teacher besides myself So basically it means to take the second (or nth) derivative? Thank you. .

Homework Statement [/B] I've tried to search this up but to no avail. How am I suppose to solve this: d2y/dx3Homework Equations N/A The Attempt at a Solution Here's what I think I need to do: 1: Square and cube y and x respectively. 2: Find the second and third derivative of y and x...

Thank you. So is my calculations accurate?

Ok, so just for clarification sakes: dgs = degrees 30<45dgs 30 = initial velocity squared 45 = projectile's angle (plug into theta) NH: R= (30)^2[m/s]/9.76 *sin2(45) NP: R = (30)^2[m/s]/9.83 * sin2(45) sin2(theta) means two things I think 1: times by two or squared 2...

Here's the photo from the book:https://i.sli.mg/I2aK7f.jpg I'm teaching myself physics so is it OK to ask you guys some questions every now and again?

I'm uploading a screenshot fro my book. Sorry I didn't do this before, I thought you guys could understand from my own example. Plus I want to solve it on my own after getting help.

I'm an idiot. Hold, up let me put the polar coordinates I have in my book to here. 90 degrees doesn't make senses as it's horizontal/vertical. EDIT: Yea, I mean polar coordinates. Apologies for the polar coordinate format. If you want, I can take a screenshot of my book. Now I'm unsure. It...

Homework Statement Here's a similar problem to the one in my book (I don't want to post the one in my book as I don't want to cheat): The gravitational acceleration on Mars is 3.719[m/s^2]. The gravitational acceleration on Earth (excluding air friction and other places) is 9.81. the initial...
