A few trig problems that require the same thing or concept. As always I appreciate the help.
1) If Tan A=1/3 and Tan B=1/2 show that Tan(1/3 + 1/2) = 1
(Tan1/2 + Tan1/3) / 1-tan(1/2)tan(1/3)
I am a little confused with this because I can't use a calculator and am confused on what exactly to do here. I don't know Tan1/2 or Tan 1/3..I know it of pie/2 and pie/3 but its not the same?
2) Tan(7Pie/4 - 1/3)
Sort of the same thing, if I figure out what to do with the 1/3 i should be good. The 7Pie/4 = 315 = -1..so is it just Tangent of -4/3?
Thanks again for taking the time
