How do you find the exact value of sin 315?
The value of sin 315 degrees can be calculated by constructing an angle of 315° with the x-axis, and then finding the coordinates of the corresponding point (0.7071, -0.7071) on the unit circle. The value of sin 315° is equal to the y-coordinate (-0.7071). ∴ sin 315° = -0.7071.
How do you find the exact value of sec?
The sec of an angle in a right triangle is the ratio of the length of the hypotenuse to the length of the adjacent side. Secant can be easily replaced by cos x using the formula, sec x = 1 / cos x.
What is the exact value of 315?
Trigonometric Function Values of Special Angles
| θ° | θradians | sec(θ) |
|---|---|---|
| 240° | 4π/3 | -2 |
| 270° | 3π/2 | 0 |
| 300° | 5π/3 | 2 |
| 315° | 7π/4 | √2 |
How do you write 315 degrees in radians?
andif you want to convert an angle from degree to radians: ar=αd⋅π180° . In our case: ar=315°⋅π180°=74π .
What is the value of cot 315 degrees?
-1
What is the Exact Value of Cot 315 Degrees? The exact value of cot 315 degrees is -1.
How do you find the sec of an angle?
The secant of an angle in a right triangle is the value found by dividing length of the hypotenuse by the length of the side adjacent the given angle. The secant ratio is the reciprocal of the cosine ratio.
How do you find the value of SEC 315?
How do you find the value of sec(315)? Assuming 315 is a value in degrees, we can rewrite that to 315º = 360º −45º, and since 360º is a full loop, we can say that Since the cosine is an even function, we have that cos( −x) = cos(x), so
How do you find the exact value of CSC 45?
Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because cosecant is negative in the fourth quadrant. The exact value of csc(45) csc ( 45) is √2 2.
What is SEC () trigonometric function?
You can calculate value of sec () trignometric function easily using this tool. In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions) are functions of an angle. They relate the angles of a triangle to the lengths of its sides.
