Click here:point_up_2:to get an answer to your question :writing_hand:find the value of displaystyle 1-tan^2 (x) = 1 - (sin 2 x)/ (cos 2 x) = [cos 2 x - sin 2 x]/cos 2 x = [cos 2x]/cos 2 x is a posibly 'simplified' version in that it has been boiled down to only cosines. If you want Read More. Explore math program. tanx = + or -1 at this point you could recognize it's a 1-1- sqr2 right triangle that's 45 degrees Or you could plug in 1 into a calculator with an inverse trig function, and it would read 45 degrees or pi/4, plug in -1 and the inverse tangent will probably say -45 degrees. Simplify both sides of the equation.
