What is the trigonometric function of 45?
Trigonometric Functions of 45° : Then OM = | x | and MP = | y |.
What is the csc of 30?
The exact value of csc(30°) csc ( 30 ° ) is 2 .
Is Cos Pi 2 undefined?
Trigonometric functions are equal to 0, 1, -1 or undefined when the angle lies on an axis, meaning that the angle is equal to 0, 90, 180 or 270 degrees (0, (pi)/2, pi or 3(pi)/2 in radians.) The value of cos (pi/2) is 0, so the secant of (pi)/2 must be undefined.
What is Arcsin equal to?
The arcsin function is the inverse of the sine function. It returns the angle whose sine is a given number….arcsin.

How many 45 CIRC 45 ∘ 45 degrees angles does it take to make a full turn?
eight 45 degree angles
Answer: It takes eight 45 degree angles to make a full turn. Full turn means turning around until it points in the same direction again.
Why is sin 45 degrees important in trigonometry?
Before discussing Sin 45 degrees, let us know the importance of Sine function in trigonometry. Sine function defines a relation between the acute angle of a right-angled triangle and the opposite side to the angle and hypotenuse.
How are trigonometric equations solved in degrees and radians?
Trigonometric equations can be solved in degrees or radians using CAST and its period to find other solutions within the range, including multiple or compound angles and the wave function. To solve trigonometric equations involving radian measure, you should proceed in the same way as for degrees.
What are the values of the trigonometric functions?
The trigonometric functions sine, cosine, tangent, cotangent, secant, and cosecant are defined as follows: It is essential that you be familiar with the values of these functions at multiples of 30°, 45°, 60°, 90°, and 180° (or in radians, π/6, π/4, π/3, π/2, and π (See Table .)
How are degrees converted to radians in calculus?
Trigonometric Functions. To change degrees to radians, the equivalent relationship 1° = π/180 radians is used, and the given number of degrees is multiplied by π/180 to convert to radian measure. Similarly, the equation 1 radian = 180°/π is used to change radians to degrees by multiplying the given radian measure by 180/π to obtain…
