Tìm cực trị của hàm số x⁴-8x²+2y²-2

The value of sin Θ is:

                   12/13

We know that the sine trignometric ratio corresponding to a given angle Θ is defined as the ratio of the side opposite to the given angle to the hypotenuse of the triangle.

i.e. sin Θ=AB/BC

Since AB is the side opposite to Θ

and the hypotenuse of the right triangle is: BC

                        Hence, we have:

                           sin Θ=12/13
