# highschool class help

i only have the math level of a grade 11, which is pre calculus 11, would i be good to take a grade 12 level calculus course? im going to be passing pre cal 11 with a 98 but im not sure if thats enough for calculus 12. are the fundamentals of calculus taught in the course? Is calculus 12 like another type of math that pre cal 11 sets you up for? im also taking going to be taking pre calculus 12 in the same semester. if i am able to with my current knowledge, can you tell me what i need to know and what i should study to be more prepared?

i didnt take calculus 11, i took pre calculus 11, but i was very good at everything in the class, we only looked at straight line formulas, parabola formulas, we didnt do anything other than that. we didnt deal with any 3d object questions, i know how to find volume but not a question like "a pool is 4 m tall, 3 meters long, and 5 meters wide. you have a hose thats outputting water at t/100 cubic meters per minute. after minutes how full with the pool be?"

i dont know the exact question but the volocity and the amount of water coming out was increasing. this was a question i was given by someone on reddit as an example of a question.

the amount of water coming out at 1 minute was 1/100 cubic meters per minute and at 2 minutes the rate of flow was 2/100 cubic meters per minute, after three minutes had elapsed the amount coming out was 3/100 cubic meters per minute

The problem you mentioned is an application of derivative. It is called related rates. See https://tutorial.math.lamar.edu/classes/calci/relatedrates.aspx

we didnt deal with any 3 d object questions about two intersecting prisms. im sure i can figure out the overlapping area of two shapes.

This is a good resource to learn about derivatives and related rates: https://tutorial.math.lamar.edu/classes/calci/DerivativeIntro.aspx

Great. I think you are prepared to take Calc 12. No need to be stressed out about it or get ahead of yourself!

are any aspects of calculus comparable to physics? i was good at that

• Erdos

Not really, the material is different. But of course Calculus has applications in Physics.

give me a second, ill give an example of a question i would have a harder time with

is that in any way on the same level of math as calculus?

(4x-1/x+2)-(x+1/x-2)=(x^2-4x+24/x^2-4) solving this

i now realize i make the denominators the same and that would probably make the final numerator factorable

I added the solution to your first question. I have spent so much time on this post. If you have additional questions you may ask them in a separate post.

unless i had to use the complete the square, i think thats what its called, am i supposed to (X^2-4x+4)+24-4
