WebJul 19, 2015 · Here's another method which has its own uses. First, send every thing to one side. ⇒ sin(3x) −cos(3x) = 0. Next, express sin3x −cos3x as Rcos(3x +λ) R is a positive real and λ is an angle. ⇒ sin(3x) −cos(3x) = Rcos(3x +λ) ⇒ −cos(3x) + sin(3x) = Rcos(3x)cosλ −Rsin(3x)sinλ. Equate the coefficients of cosx and sinx on both sides. WebSolution: At x 1 = 0, the tangent line y= 2x+ 4 has an x-intercept of 2, so x 2 = 2 .
