Values of Trigonometric ratios for 0, 30,45, 60 and 90 degrees I have noticed that students cannot actually remember values of six trigonometric ratios (sin, cos, tan, cosec, sec and cot) for 0, 30, 45, 60 and 90. These values are used very often and it is

We learned about sin 60 degrees value along with other degree values here, this far. Also, derived the value for cos degree and tan degrees with respect sin degrees and also in terms of radians. In the same way, we can find the values for other trigonometric ratios like sec, cosec and cot.

Suppose the 30 unit vector is acting horizontally. Then the 60 unit vector has a horizontal component of 60*cos(60) units and a vertical component of 60*sin(60) units. So total horizontal = 30 + 60*cos(60) = 60 units total vertical = 60*sin(60)= 51.96 units. Then magnitude

The key angles in trigonometry can be demonstrated by two triangles, an equilateral triangle with sides of 2 units and an isosceles (equal legs) triangle with equal legs of 1 unit each. The equilateral triangle must be divided by a perpendicular b
