Prove: 1/cos2A+sin2A/cos2A=sinA+cosA/cosA-sinA

Sin23=p write cos113 in terms of p

f(x)=sin2x and g(x)=1/2tanx for x is the element of [-90;180] 8.1)calculate the x-coordinates of the points of intersection of f and g.

Find a geometric series which has a third term of 7/4 and a sum to infinity of 14.

A sequence is formed by adding together the corresponding terms of a geometric sequence and and an arithmetic sequence.The common ratio of the geometric sequence is 2 and the common difference of the arithmetic sequence is 2.The first term of the new sequ...

Use the formula: A=P(1+i)^n A=? P=$5000 i=2.5/2 =1.25/100 =0.0125 n=2*18=36 now we substitute: A=5000(1+0.0125)^36 =5000(1.0125)^36 =$7819.72

1)T2-T1=T3-T2 2x+6-(x-2)=4x-8-(2x+6) 2x+6-x+2=4x-8-2x-6 x+8=2x-14 x=22 2)substitute for x: 1st term:x-2=22-2=20 2nd term:2x+6=2(22)+6=44+6=50 3rd term:4x-8=4(22)-8=88-8=80 now we look for the constant difference(d): T2-T1=50-20=30 T3-T2=80-50=30 So d=30 T...
