if you know SOH CAH TOA, and you have cos given, then you can fill in the remaining legs and angle of the triangle using 'sin' and Pythagorean theorem. It might help if you start by drawing a right angled triangle. Call one of the angles for theta, and then fill in the one leg and the hypotenuse using the values given by cos (theta)

|dw:1369876988964:dw| Now to find the 'vertical' side of the triangle you can use Pythagorean. And once you have that length you can fill in the other trig ratios sin, cos, tan tan = sin / cos csc = 1/sin sec = 1 / cos cot = 1 / tan

  • jkristia
you are given cos (x) = 2/5, and you know cos (x) = adjacent / hyp, so there you are given 2 sides
jkristia
  • jkristia
Think of trig functions as ratios. Cos (x) gives you a ratio of the adjacent (horz) side divided by the hyp side
jkristia
  • jkristia
correct, so you found the 'opposite side' (I have to run, so I don't have time to double check right now)
jkristia
  • jkristia
on the vertical side, that is the length you just found
jkristia
  • jkristia
have to run - sorry

sin= opp/hyp cos=adj/hyp tan=opp/adj cosec=hyp/opp sec=hyp/adj cot=adj/opp put the values you will get all the 6 quantities
