Explanation: the cot function may be written as: cotx = cosx sinx. hence cot( π 2) = cos(π 2) sin(π 2) = 0 1 = 0. Answer link. 0 >the cot function may be written as: cotx = cosx/sinx hence cot (pi/2) = cos (pi/2)/sin (pi/2) = 0/1 = 0.Mar 17, 2018 · (2+sqrt3)/2. Knowing that, (1+costheta)=2cos^2(1/2theta), we have, 1+cos(pi/6)=2cos^2(1/2*pi/6), i.e., 1+sqrt3/2=2cos^2(pi/12). rArr cos^2(pi/12)=(2+sqrt3)/2. ….

"The fundamental trigonometric identities" are the basic identities: •The reciprocal identities. •The pythagorean identities. •The quotient identities. They are all shown in the following image: doc inmate search new jerseycharlotte russe heelstw wikipedia For example, we define the two major circular functions, the cosine and sine in terms of the unit circle as follows. Figure 1.2.1 1.2. 1 shows an arc of length t t on the unit circle. This arc begins at the point (1, 0) ( 1, 0) and ends at its terminal point P(t) P ( t). We then define the cosine and sine of the arc t t as the x x and y y ...In the sum of angle theorems, let a=b so that \cos(2a)=\cos^2(a)-\sin^2(a) By the last identity, notice that \cos^2(a)-\sin^2(a)=2\cos^2(a)-1 \cos^2(a)-\sin^2(a)=1-2\sin^2(a) Now let a=\pi/4 ...
