The key here is to realise that tanx = sinx/cosx. If we write out ... 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 1, 2011 ... i.e. tanx = 1. This means (in this interval) that x = π/4. So π/4 is the only critical number. This means we have to check the points 0, π/4 ... sinx tan x = sin x for 0≤ x < 2π . a) π -- 4, b) π 5π --, --- 4 4, c) π 0 ... ⇒ sin x tanx - sin x = 0 ⇒ sin x(tanx - 1. It follows that. sin x = 0 ⇒ x ... Apr 6, 2013 ... My advice on proving trig identities is 1) change all functions on one side to sine and cosine 2) use the fundamental identity, cos^2(x) + sin^2(x) = 1 3) if ... Jan 27, 2019 ... By solving the equation 1+cotx1+tanx​=2, we find that one numerical value of a trigonometric function is tanx=2.
