Why we use sine angle in cross product while cos angle in dot product?
Zariashah
Because in dot product we take projection fashion and that is why we used cos and similar in cross product we used sin

What is sine of angle 22.5 degrees?
The sine of 22.5 degrees is 0.383
Is sine greater than one?
No angle has a sine function greater than 1.
What ratio correctly describes the sine function?
In a right triangle, the sine of an (non right angle) angle would the ratio of the opposite side (opposite to the angle selected) and the hypotenuse
In a right triangle the sine of any angle is?
The longest side of the right angles triangle is called the hypotenuse. Divide the length of the side opposite the chosen angle by the length of the hypotenuse. This is the Sine of the angle.
Why is the sine of 90 degrees equal to 1?
Sine = Opposite divided by Hypotenuse Opposite is the side of the triangle opposite the angle (in this case the 90o angle). Hypotenuse is the side opposite the right angle in a right angle triangle. Therefore, Sine 90 = 1 because the opposite side and the hypotenuse are the same side, they are both opposite the right angle.
Why you use cosine theta with cross product?
Normally you use sine theta with the cross product and cos theta with the vector product, so that the cross product of parallel vectors is zero while the dot product of vectors at right angles is zero.
Can the vector product of two vectors be negative?
no .....the scalar product of two vectors never be negative Yes it can If A is a vector, and B = -A, then A.B = -A2 which is negative. Always negative when the angle is between the vectors is obtuse.
The sine of a 30 degrees angle equals what?
the sine of a 30 degree angle is 0.5
What is the size of an angle when the sine is 6352?
the sine of an angle can't be greater than 1.0
Is sine of an angle directly proportional to an angle?
No. The sine of an angle is not directly proportional to the angle. It is a function of the angle, but it is periodic, repeating every 360 degrees of the angle.
How does kvar work?
kvar can be calculated as follows the a product KVA andt the sine of the angle between the KVA and KW.
How calculate kvar?
kvar can be calculated as follows the a product KVA andt the sine of the angle between the KVA and KW.
What is the sine of angle of incidence divided by the sine of angle of refraction of equal optical density?
It is 1.
What is sine theta?
The sine theta of an angle (in a right triangle) is the side opposite of the angle divided by the hypotenuse.
What is sine in trigonometric function?
Sine of an angle (in a right triangle) is the side opposite of the angle divided by the hypotenuse.
How do you figure out the sine of a triangle?
An angle can have a sine ratio, not a triangle.
The sine of an angle is equal to what ratio?
Sine = opposite / hypotenuse
