That is, we can write it mathematically as sec θ = Hypotenuse / Base. Also, we know that the secant function is the reciprocal of the cosine function. Therefore ...

Use the angle on the unit circle to find the corresponding x and y-coordinates. For π, x = −1 and y = 0. sinπ=y=0, cscπ=1y=10=undefined. cosπ=x=-1, secπ=1x=1-1= ...

20 июл. 2020 г. · For sec θ extend the terminal side of θ until it intersects the vertical tangent drawn to the circle at (1, 0). The length of the hypotenuse of ...

The formulas for csc sec cot are given below: csc x = Hypotenuse / Perpendicular (OR) Hypotenuse / Opposite Side; sec x = Hypotenuse / Base (OR) Hypotenuse / ...
