We help you live your dreams. Get access to our extensive online coaching courses for IIT JEE, NEET and other entrance exams ... Mar 2, 2018 ... Explanation: If tanx=1 , then sinx=cosx . We know this is true for x=π4 as a base case. ... p=nπ , where n is an integer. ... The first positive ... The period of the tan(x) tan ( x ) function is π π so values will repeat every π π radians in both directions. x= ... 1 - tan(x) tan(y). DIFFERENCE IDENTITIES sin(x - y)=sin(x) cos(y) - cos(x) sin(y) cos(x - y) = cos(x) cos(y) + sin(x) sin(y) tan(x) ... 1. 1 y = tan(x) y. You can put this solution on YOUR website! %28sinx%2Btanx%29%2F%281%2Bsecx%29=sinx tanx is the same as sinx%2Fcosx %28sinx%2B%28sinx%2Fcosx%29%29%2F%281 1 − x2, x ∈ [0,1]. It follows that the value of. Z 1. 0 p. 1 − x2dx is precisely the area of the portion of the unit disk ... − 1. 2 tan x. 2. + 2 ! + C. 2. 1/(1 + sin2 x) is best integrated using u= tanx.
