Tan 2 theta in terms of cos theta
WebFor instance, if you were writing 3x+7y-4z in terms of x, and you know that y=2x and z=1/2x, you would write it as 3x+7(2x)-4(1/2x) or 3x+14x-2x. With these problems (sin, cos, tan, sec, csc, cot) you would need to replace tan, sec, csc, and cot as sin/cos, 1/cos, 1/sin, and cos/sin respectively. tan + cos - sec would be rewritten as sin/cos ... WebAug 7, 2013 · tan^2 = sin^2+cos^2 = 1 << this we can agree on the solutions tell us to divide both sides by cos^2. so sin^2/cos^2 + cos^2/cos^2 = 1/cos^2 and 1/cos^2 is sec^2 << still following then …
