  • trigonometry -

    for the problem:
    sin(x) * cos(x) = 0
    What values of x will result in cos(x)=0 or sin(x)=0?
    Hint: in the domain of 0<=x<(2*pi), there are 4 values.

  • trigonometry -

    simplify the trigonometric expression.

    I have to find an exact solutions on the interval [0,pi) for both of these problems-- 1) 2sin2x = sqrtx and 2) 1-2sqrt2 sinxcosx = 0 I know this much: 1) sin2x = (sqrt x)/2 = 2sinxcosx = (sqrt x)/2 What do I need to do next?

    ( tanx/1-cotx )+ (cotx/1-tanx)= (1+secxcscx) Good one! Generally these are done by changing everything to sines and cosines, unless you see some obvious identities. Also generally, it is best to start with the more complicated side …

    this is for proving identies and its fustrating i can't solve this one question! lol x=feta (btw the first part is supposed to be divided by the bottom) 1 + 2sinxcosx + sinxcosx sinx + cosx (1 + 2sinxcosx / sinx + cosx) + sinxcosx
