If sin theta=3/5 and theta is in quad 2 the exact form of csc (pi/2-theta) is...? Tried figuring out this before lets try this again

    Which I did and you clearly said my solution made no sense as well as your explanations @campbell_st and if you look back at my previous questions I have solved them myself with actual help

    ok... here is a really simply start, below is a right triangle |dw:1436660262409:dw| what is the size of x, and how did you calculate it

    this idea, may seem trivial, but it is the key to being able to solve this problem... here is another question in terms of radians |dw:1436660476966:dw|

    here is how these 2 questions apply to your question |dw:1436660720512:dw||dw:1436660750360:dw|

    so drawing a diagram of your question |dw:1436660808410:dw| remembering you are on the number plane, what is the size of a, it can be found using pythagoras' theorem...

    then tell me what is the size of angle x..?

    describe angle x in term so a size... \[x = \frac{\pi}{2} - ....?\]

    See? this gets me nowhere what kind of math is this? Nowhere did the previous helpers show me frickn triangles and angles I didnt ask the question again to get the same response @campbell_st

    well to get a solution you need to work through it... Open Study isn't about giving people answers to questions... its about help with understanding. And just to put the question is persective... this is at the high end of difficulty for right triangle trigonometry questions... there are several steps and several concepts that are needed to solve it... concept 1 in a right triangle you have 1 angle = 90 or pi/2 so the other 2 angles must add to 90 or pi/2 is 1 angle is x then the other angle has to be 90 - x or pi/2 - x this seems to be an idea you don't understand |dw:1436661501625:dw| does that make sense...?

    and the next task is to show the angle in the 2nd quadrant.... because that's what you are asked to do... using the fact that sin = 3/5 so if you form a triangle, what is the measure of the other side..?

    Nobody just gave me the answer they helped me through telling me what was right or wrong so openstudy doesn't work like that obviously. @campbell_st and what I said before isn't it -4/5 the other side

    my advice for trigonometry is to 1 draw a diagram |dw:1436662047521:dw| 2. use the basic ratios sin cos and tan what is the value of \[\sin(\frac{\pi}{2} - \theta) = ..?\]

    Forget it I'm done please don't answer this question again if I post it because this is the second time I got nothing

    ok... I'll leave it.... but I'd suggest you learn about the complementary angle in a triangle... as its the key to this question.... and If you were able to find \[\sin(\frac{\pi}{2} - \theta) = ...?\] then all you need to do is take the reciprocal to find \[\csc(\frac{\pi}{2} - \theta)\] as an exact value.... so good luck...

    What the heck is theta anyways? I don't know what theta even is

    I'll let someone else answer that for you
