The period of the tan(x) tan ( x ) function is π π so values will repeat every π π radians in both directions. x= ... Jul 20, 2020 ... Since tanx = sinx/cosx, anywhere on the unit circle where sinx = cosx is where tanx = 1 which is where x = π/4 or x = 5π/4. Feb 6, 2024 ... Answer ... Step-by-step explanation: To prove that sinx + cosx / sinx - cosx = tanx + 1 / tanx - 1, we'll simplify both sides of the equation and ... Sep 16, 2020 ... sec x - tanx = (1/cosx) - (sinx/cosx) = (1-sinx)/cosx secx+tanx = (1+sinx)/cosx the product of the two is (1-sinx)( Mar 11, 2008 ... 1 = tan x + sec x = (sin x + 1)/cos x = (-cos(pi/2 + x) + 1)/sin(pi/2 + x) = 2sin²(pi/4 + x/2)/(2sin(pi/4 + x/2)cos(pi/4 + x/2)) = tan(pi/4 + x ...
