Calculus
yes that's what I did I just wasn't sure if I came up with the correct answer ?

Calculus
complete the identity sinq / cosq + cosq / sinq = I'm not sure I'm coming up with 1 + cot q

Try and draw it out The pythagorean theorm says a^2 + b^2 = c^2 15.5^2 + 14^2 = c^2

I don't know what I mean I'm very confused , just disregard intil I cn puit more info in there

oh ok sorry I'll try to be more specific

Calculus
cosine ( x,y) csc(theta,or angle)I don't have a theta symbol om my keyboard and they use that interchangable in my book

Calculus
Use the given information to find the cos (2,0), csc q = 5/3, q lies in n quadrant II How would I go about doing this

math-triangle help
This is how I would do it. Pythagorean theorem: a2 + b2 = c2. a^2 + 4^2 = 11^2 a^2 +16 = 105 subtract both sides by 16 a^2 - 16 = 105 - 16 a^2 = 105 a = sqrt 105 a = 10.247

I don't doubt you it doesn't make sense to me either but those are the choices I'm given let me look into this a little more and I'll re-post if need be

Math
My options are -1/2 sqrt2 + sqrt2 1/2 sqrt2 + sqrt-2 -1/2 sqrt2 - sqrt2 1/2 sqrt2 + sqrt2
