How do you find the exact value of sin pi 12?
Explanation:
- cos(2π12)=cos(π6)=√32=1−2sin2(π12)
- 2sin2(π12)=1−√32=2−√32.
- sin2(π12)=2−√34.
- sin(π12)=±√2−√32.
- sin(π12)=√2−√32.
What is value of sin pi?
What is the value of sin pi? In trigonometry, we use pi (π) for 180 degrees to represent the angle in radians. Hence, sin π is equal to sin 180 or sin π = 0.
What is sin theta equal to?
As per the sin theta formula, sin of an angle θ, in a right-angled triangle is equal to the ratio of opposite side and hypotenuse. The sine function is one of the important trigonometric functions apart from cos and tan.
What is the Y-intercept of Y COSX?
The y-intercept of this function is the point where the line “crosses” the y-axis. In other words, it’s where “x” is 0. That makes this easy to find; all you have to do is plug in 0 for x to get y. So the y-intercept is 1.
What is the maximum value of y Sinx?

Can an amplitude be negative?
The amplitude or peak amplitude of a wave or vibration is a measure of deviation from its central value. Amplitudes are always positive numbers (for example: 3.5, 1, 120) and are never negative (for example: -3.5, -1, -120).
What is negative sine?
The sine of an angle is: \displaystyle \frac{opposite}{hypotenuse} For our data, this is: \displaystyle \frac{8}{\sqrt{73}} Since this is in the third quadrant, it is negative, because sine is negative in that quadrant.
Can a frequency be negative?
Real sinusoidal signals have only positive frequency. Negative frequency is an idea associated with complex exponentials. That one with the negative exponent is where you get the concept of a negative frequency.
What does a negative slope look like?
A negative slope means that two variables are negatively related; that is, when x increases, y decreases, and when x decreases, y increases. Graphically, a negative slope means that as the line on the line graph moves from left to right, the line falls.
How do you know if a slope is right?
Using the Slope Equation
- Pick two points on the line and determine their coordinates.
- Determine the difference in y-coordinates of these two points (rise).
- Determine the difference in x-coordinates for these two points (run).
- Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).
What is the exact value of tan 60?
Therefore, the exact value of Tan 60 degrees is √3.
How do you work out tan 60?
To find the value of tan 60 degrees geometrically, consider an equilateral triangle ABC since each of an angle in an equilateral triangle is 600. Draw a perpendicular line AD from A to BC….Learn More:

What is the reciprocal of tan?
There are three reciprocal trigonometric functions, making a total of six including cosine, sine, and tangent. The reciprocal sine function is cosecant, csc(theta)=1/sin(theta). The reciprocal tangent function is cotangent, expressed two ways: cot(theta)=1/tan(theta) or cot(theta)=cos(theta)/sin(theta).
