i think i need alittle more guidance ok so from this point where i have the derivative of what u gave me, i can set it equal to zero and find the maximum for the angle, or is there more that i still need to do(ie more deriving). also it would help me a lot if u cud tell me where u got ur trig...

little more help i understand that i must use the chain rule, but i don't know which terms are constants, for example vcosA and 2gYo. would i have to make them equal zero because of constant rule or no

i was given a problem and found that x = (VcosA)/g*(VsinA + ((VsinA)^2 + 2gYo)^1/2) where x is the distance v is the speed A is the angle g is the force of gravity and Yo is the height but i am a bit lost in taking its derivative. once i do so, i need to...

My question is, derive an equation to find the maximum range of a projectile that's not on level ground. I am lost and i did attempt this, by making a diagram and subbing in what i thought i would need to use, but i still have not come up with the answer. please help

thx thanks for ur hellp and all and I am sorry i was a pest i solved it differently from how u showed me tho

im really slow can u please write out step by step waht to do. I am really slow sir please

yes yes i did but i can't solve for either cos thada or sin thada

ty thatnks for ur help but i still don't understand what to do so i was wondering if u could coach me through it

here was the original question. in the design of a super market, there are to be several ramps connecting different parts of the store. cusomers will have to push grocery carts up the ramps. An engineer has done a survey and found that almost no one complains if the force require is no more that...
