The sine of 45 degrees is equal to (\frac{\sqrt{2}}{2}). This value arises from the properties of a 45-45-90 triangle, where both legs are equal and the hypotenuse is (\sqrt{2}) times the length of each leg. Consequently, the sine function, which is defined as the ratio of the opposite side to the hypotenuse, yields this result for 45 degrees.

Is theta greater than 45 degrees?

To determine if theta is greater than 45 degrees, you need to know the specific context or value of theta. If theta is an angle measured in degrees and is specifically stated as being greater than 45, then yes, it is greater. Otherwise, without additional information, it's impossible to conclude definitively.

What is the arc sine of 1.5 degrees?

if x if ArcSine 1.5 degrees means the sin(x)=1.5 but the range of the sin(theta) for all angles theta is between o and 1 inclusive. So there is no real answer.


Why does cos negative theta equals positive theta?

You must think of the unit circle. negative theta is in either radians or degrees and represents a specific area on the unit circle. Remember the unit circle is also like a coordinate plane and cos is the x while sin is the y coordinate. Here is an example: cos(-45): The cos of negative 45 degrees is pi/4 and cos(45) is also pi/4
