-cos(x) + tan(x)^ two /x - (-x + tan(x))/x^ two = zero
minus co sinus of e of (x) plus tangent of (x) squared divide by x minus ( minus x plus tangent of (x)) divide by x squared equally 0
minus co sinus of e of (x) plus tangent of (x) to the power of two divide by x minus ( minus x plus tangent of (x)) divide by x to the power of two equally zero
-cos(x) + tan(x)2/x - (-x + tan(x))/x2 = 0
-cosx + tanx2/x - -x + tanx/x2 = 0
-cos(x) + tan(x)²/x - (-x + tan(x))/x² = 0
-cos(x) + tan(x) to the power of 2/x - (-x + tan(x))/x to the power of 2 = 0
-cosx + tanx^2/x - -x + tanx/x^2 = 0
-cos(x) + tan(x)^2 divide by x - (-x + tan(x)) divide by x^2 = 0
