Use power series operations to find the taylor series of cos2(x)cos2⁡(x) at the point a=0a=0. your answers should not include the variable xx. finally, determine the general term anan in cos2(x)=∑n=0[infinity]anx2ncos2⁡(x) =∑n=0[infinity]anx2n. hint: cos2(x)=(1+cos2x)/2.cos2⁡(x)=(1+cos ⁡2x)/2.

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.
