What is larger sine A or tangent A in an acute angle?
tangent will always be larger because its denominator is smaller than sine's.
What is sinAB?
There is no simplifying formula for the sine of a product of two angles.
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
Is the sine of an angle positive?
The sine of an angle between 0 and 180 degrees is positive. The sine of an angle between 180 degrees and 360 degrees is negative. At 0, 180 and 360 degrees the sine is 0.The sine is a periodic function with period 360 degrees, so angles differing by a multitude of 360 degrees have the same sine. Hence, for instance, the sines of the angles 0, 360, 720, ... are equal, namely 0.In any right triangle the sine of one of the non-right angles will be positive, since these are greater than 0 and less than 90 degrees.
What is the meaning of degrees and 'in sine laws?
It is one unit of measure of angles.
What is snell's law for angles and velocities and wavelengths?
The Sine of incidents ---------------------------- The sine of refraction
What is larger sine A or tangent A in an acute angle?
tangent will always be larger because its denominator is smaller than sine's.
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)
Sine bar is used to measure?
sine bar is used to measure the angles of given work pieces
Are The sine and cosine of acute angles equal?
The sine and cosine of acute angles are equal only for 45° sin45° = cos 45° = 1/sqrt(2) = 0.7071
What is sinAB?
There is no simplifying formula for the sine of a product of two angles.
How do you work out the angles in a triangle with only 3 sides and no angles?

How does one differentiate between the sine rule and the sine ratio?
The sine rule(also known as the "law of sines") is: a/sin A = b/sin B = c/sin C where the uppercase letters represent angles of a triangle and the lowercase letters represent the sides opposite the angles (side "a" is opposite angle "A", and so on.) Sine Ratio(for angles of right triangles): Sine of an angle = side opposite the angle/hypotenuse written as sin=opp/hyp.
Is the sine of an angle positive?

What is sine in trigonometry?
The sine of one of the acute angles in a right triangle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.
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.
