thanks for the response. i figured out the problem. but thanks

Homework Statement Two 10 kg masses are placed on an x-y coordinate plane measured in meters. the first mass is at position (0,0) and the second at (2,0). that's the first part of the problem the second part is: if an additional 5 kg mass is placed at the point K, calculate the gravitational...

thanks i figured it out. i forgot that sin(x-y)=sinxcosy-sinycosx

[SOLVED] Solving for X help Homework Statement sin(60-x)=2sinx need to find x i have no idea on how to solve it.

oh i get it thanks i was adding the top part properly but not hte bottm part. thanks

[ (1/cos) + (1/sin) ] / [ 1 + (sin/cos) ] that's the original problem. how did you get csc from that?

maybe that's wrong then (1/cos + 2/sin + cos/sin^2), also i tried multiplying by cosx and i get 1/sin + cos - 1/cos i tried going further but it seems like I am doing something wrong. does anyone have the solution yet?

yea sorry for not being clear. and i already tryed replacing them by the definition. i just end up with 1/cos + 2/sin + cos/sin^2

its not that its, sec+csc and all that over 1+tan. sec+csc .............1+tanignore the the dots the problem i am and talking about is in the the top right also (sec+csc)/(1+tan)

i have to simplify sec+csc/1+tan

Homework Statement sec+csc/1+tan The Attempt at a Solution i tried simplifying it and the farthest i got was: 1/cos + 2/sin + cos/sin^2 im not sure that's even right

thanks i got

I need help on graphing cosine and sine functions. i know how to read a graph and come up with the equation but i don't know how to do it the other way around. i want to be able to graph something like y=-2+2cos0.5x

thanks the equation works. i got one question tho. how did you get from this V+TKV=TG+Vo to this V(1+TK)=TG+Vo?

did anyone figure it out yet?
