Tan 90 value

the value it give is 557135813.94455. does the value will remain same every time?? why its not showing infinity?? #include #include #define PI 3.14159265 int main () Code is not asking for the tangent of 90°, but the tangent of a number, in radians, close to 90°.

• • • • The tan value when angle of a right triangle equals to $90^°$ is called tan of angle $90$ degrees. It is mathematically written as $\tan$ is infinity in trigonometry.

Tan 90 Degrees The value of tan 90 degrees is not defined. In Trigonometry, Sine, Cosine and Tangent are the three primary ratios, based on which the whole trigonometric functions and formulas are designed. Each Usually, the degrees are considered as 0°, 30°, 45°, 60°, 90°, 180°, 270° and 360°. In this article, we will discuss, how to find the value for tan 90 degrees along with other degrees or radians. Tan 90 is equal to infinity (∞) or undefined Value of Tan 90 Degrees The exact value of tan 90° is: Tan 90 Degree = Not Defined Note: Tan 90 = Cot 0 = ∞ How to Find Value of Tan 90 As discussed, when we speak about trigonometry, Sine, Cosine and Tangent are the principle trigonometric functions. Let us give a brief about all three functions or ratios with respect to a right-angled triangle. Sine functions denote that for a given right-angled triangle, the sin of angle θ is equal to the ratio of the opposite side to the angle, and hypotenuse. Sin θ =Opposite Side/Hypotenuse Cosine function denotes that for a given right-angled triangle, the cos of angle θ is equal to the ratio of the adjacent side to the angle, and hypotenuse. Cos θ =Adjacent Side/Hypotenuse Tangent function denotes that for a given right-angled triangle, the tan of angle θ is equal to the ratio of the opposite side to the angle, and adjacent side or base. Tan θ = Opposite Side/Adjacent Side We can also represent the tangent function as the ratio of the sine function and cosine function. ...
