WebIf x+y=π/4 ,prove that (1+tanx) (1+tany)=2 Solution Solution: Given: or, x + y = pi/4 So: or, tan (x+y) = tan (pi/4) or, tan (x+y) = 1 We know that: [tan (pi/4) = 1] [tan (x+y) = … WebSo again, using the power rule, we take the power times anything in front of the function times the X squared plus y squared plus C squared to the one less power So they'd be …

WebExample 1: Determine the value of tan2x if tan x = 4/3. Solution: We know that tan2x = 2tan x / (1 − tan 2 x). If tan x = 4/3, we have tan 2 x = 16/9. tan2x = 2tan x / (1 − tan 2 x) = 2 (4/3)/ (1 - 16/9) = (8/3)/ (-7/9) = -24/7 Answer: tan2x = -24/7 Example 2: Find the value of tan2x if sin x = 12/13 and cos x = 5/13 tree of life jewish

Web16 apr. 2015 · 1 Answer bp Apr 16, 2015 It is a trignometrical identity, there is nothing there to solve. The identity is arrived at by simplifying the identities in sin(x + y) cos(x + y) = sinxcosy + cosxsiny cosxcosy − sinxsiny. Divide the numerator as well as the denominator by cos x cosy to get tanx + tany 1 − tanxtany Answer link tree of life jennifer iacovelli
