The sine of the angle gives the length of the y-component (the opposite to the angle or the rise) of the triangle, the cosine gives the length of the x-component (the adjacent of the angle or the run), and the tangent function gives the slope (y-component divided by the x-component)

The sin and cos are called trigonometrical ratios. In a right angled triangle sin of an angle is defined as the ratio of Perpendicular with respect to the reference angle to it's Hypotenuse. Similarly cos of an angle is refined as the ratio of base of the triangle corresponding to the reference angle...

I am confused... !!! Plz help. Thanx
