Formula for tan 2 theta
WebSep 16, 2016 · tan(θ 2) = sinθ = 2tan(θ 2) 1 + tan2(θ 2) So, tan( θ 2)((1 + tan2( θ 2) − 2) = 0 And so, tan(θ 2) = 0 gives θ 2 = kπ,k = 0,1,2,3,.. the other factor = 0 gives# tan^ (theta/2)=1 to tan (theta/2)=+-1 to theta/2=kpi+-pi/4#. Combining both for values of θ ,. θ = 2kπ and θ = (2k ± 1 2)π,k = 0,1,2,3,... Answer link Nghi N. Sep 16, 2016 WebFormula sec 2 θ = 1 + tan 2 θ The square of secant function equals to the addition of one and square of tan function is called the secant squared formula. It is also called as the square of secant function identity. Introduction The secant functions are sometimes involved in trigonometric expressions and equations in square form.
