What angle is Sine and cosine equal?
at a 45 degree angle, or pi/4
How do you find the cosine and the sine?
Sine= Opposite/ Hypotenuse Cosine= Adjacent/ Hypotenuse
Is the sine of an acute angle is greater that 1?
No. The sine of an acute angle is less than 1. An acute angle is less than 90 degrees. The sine of 0 degrees is 0, and the sine of 90 degrees is +1. So the sines of the angles between 0 degrees and 90 degrees are less than 1.
The sine of a 37 degree angle equals?
it is a acute angle because acute angles are less than 90degrees so basically the answer is............ 0.602 mayo.fo.sho
What is the sine of 45 degress?
√ 1/2 = sine(45)= cosine(45) -Key
How do you find sides of right triangle given only the hypotenuse and all angles?
One is the hypotenuse times the sine of one acute angle, the other, the hypotenuse times the sine of the other acute angle (or the cosine of the first).
Do the equations sine plus cosine and sine squared plus cosine squared both equal 1?
No, they do not.
Which angle has a negative sine and a positive cosine?
All the angles in 4th quadrant have positive cosine and negative sine e.g. 280,290,300,310...etc.
Does tangent of x equal cosine divided by sine?
No, it does not.
What is cosine squared theta equal to'?
Cosine squared theta = 1 + Sine squared theta
How do you work out the angles in a triangle with only 3 sides and no angles?
use the inverse sine or cosine or tangent
What does sin mean in trig?
its short for sine. theres sine, cosine, and tangent. sine is opposite over adjacent for the sides of a triangle (or angles)
What is the six trigo function of acute angle?
Sine, Cosine, Tangent, Cosecant, Secant, Cotangent.
Why are the sine and the cosine of an acute angle always less than 1?
Well, the easiest way to go at it is simply to remember thatthe sine and cosine of any angle are always less than 1 .
How do you solve for a triangle with two angles but no lengths?
you can use the sine, cosine, tangent formula.
What are the six trigonometric functions of special angles?
sine, cosine, tangent, cosecant, secant and cotangent.
What is the equation for finding the sine and cosine and tangent of a triangle?
For finding the angles in a right angled triangle the ratios are: sine = opposite divided by the hypotenuse cosine = adjacent divided by the hypotenuse tangent = opposite divided by the adjacent
