Given that the final edge of angle a passes through point P (x, - 2) (x ≠ 0), and COS a = √ 3x / 6, find sin a and Tan a RT

P (x, - 2) = √ (x ^ 2 + 2) = √ (x ^ 2 + 2) = √ (x ^ 2 + 2) cosa = x / √ (x ^ 2 + 2) = √ 3x / 6 square x ^ 2 / (x ^ 2 + 2) = 3x ^ 2 / 361 / (x ^ 2 + 2) = 1 / 12x ^ 2 = 10x = √ 10, so Sina = - √ 2 / √ ((√ 10) ^ 2 + 2) = - √ 6 / 6tana = - √ 2 / √ 10 = - √ 5 / 5

1. If the final edge of the angle α falls on the line y = - 3x, find the values of sin α and cos α. Also, find the domain of COS (SiNx) under the function y = radical. Take a point P (1, - 3) on y = - 3x. Then | OP | = √ 10, sin α = - 3 / √ 10, cos α = 1 / √ 10

Given that the final edge of the angle α falls on the straight line y = 3x, find the value of sin α and Tan α quickly!

Because the final edge of the angle α falls on the line y = 3x, and the slope of the line is 3,
So tan α = 3, so sin α / cos α = 3
sinα/√[1-(sinα)^2]=3
sinα=3√[1-(sinα)^2]
(sinα)α=9[1-(sinα)^2]
(sinα)^2=9-9(sinα)^2
(sinα)^2=9/10
sinα=±(3√10)/10
cosα=3sinα=±(√10)/10

It is known that P is a point on the line y = - 3 / 4. The final edge of angle a passes through point P and sin a < 0. Find Tan A and COS a

The slope of the line k = - 3 / 4
tana=k=-3/4
It's Y / x = - 3 / 4, y = - 3x / 4
r=√(x²+y²)=√(x²+9x²/16)=5x/4
So Sina = (- 3x / 4) / (5x / 4) = - 3 / 5
