WebTherefore, the left-hand side of the given equation can be expressed in the form 2cos(x − (−60 )) = 2cos(x +60 ). So the given equation becomes 2cos(x+60 ) = 2 that is cos(x +60 ) = 1 We seek angles with a cosine equal to 1. Given that x lies in the interval 0 < x < 360 then x +60 will lie in the interval 60 < x +60 < 420 Websin2x = tanx Take everything to left hand side, so LHS equals 0sin2x - tanx = 0Recall double angle formula : sin2x = 2sinxcosx, also notice that tanx can be written as sinx/cosx giving us:2sinxcosx - sinx/cosx = 0 (gives us everything in terms of sinx and cosx)Multiply everything by cosx to get rid of the fraction2sinxcos 2 x -sinx = 0Notice sinx is common in …
