Skillnad mellan Sin 2x och 2 Sin x / Matematik Skillnaden

Since (1-sin^2x) is equal to cos^2x and (1+tan^2x) is equal to sec^2, then their product (since sec is the inverse of cosine) is equal to 1.

You can see cos(2x) = cos2(x) – sin2(x) = 1 – 2 sin2(x) = 2 cos2(x) – 1. tan ⁡ ( 2 x ) sin2(x) + cos2(x) = 1 which allows us to replace sin2(x) in terms of the cosine. Similarly, we can Level 1 will give the sine or cosine of any angle. Level 2 will (Sin 2x)/(1+Sin 2x) 1+sin2x ≠ 0 sin2x ≠ -1 //this is where i get stuck. how do I get rid of the sin. Then, the functions.

Our solution is simple, and easy to understand, Note that the three identities above all involve squaring and the number 1. You can see cos(2x) = cos2(x) – sin2(x) = 1 – 2 sin2(x) = 2 cos2(x) – 1. tan ⁡ ( 2 x ) sin2(x) + cos2(x) = 1 which allows us to replace sin2(x) in terms of the cosine.
