Question

mathmale · Answer

Hello!  First, could you say in which Quadrant the terminal side of this angle will lie?  Knowing the answer to that would make it easier to draw a picture of this terminal side, which in turn would make it easier to answer the question youve posed.

this is an essay question o.o it has no answers

mathmale · Answer

All the more reason for knowing the ropes of solving such a problem.  Please, would you try to answer my question (which quadrant?)?

lovelyharmonics · Answer

how would you go about finding that?

lovelyharmonics · Answer

i know the different quadrents... i just dont know how you would figure out where the equation goes

Where would a 90-degree angle end?  Hint:  move counterclockwise, not clockwise, from the angle zero (0).

lovelyharmonics · Answer

okay so inbetween q2 and q3

mathmale · Answer

that'd be 180 degrees.

lovelyharmonics · Answer

so q1 and q2

mathmale · Answer

90 deg. forms the border between Q1 and Q2.  This is the "terminal side" of 90 deg.

Now, where do you think the terminal side of the angle 45 deg   would be?  Draw it if you can.
