What else can I help you with?
Why are cosines positive and negative?
Because the cosine of some angles is positive and the cosine of some other angles is negative.
What are negative quadrant angles?
using protactor, we use to draw angles in anticlockwise direction and that angles are called positive quadrant angles. and angles in clockwise direction, these angles are called negative quadrant angles.
Is there a positive or a negative angle?
Yes. Angles may be measured from the direction of the positive horizontal axis and, clockwise is negative, anticlockwise is positive.
What figure has the most obtuse angles?
There is no limit to the number of obtuse angles a figure can have. A regular n-gon has n obtuse angles where n is any positive integer greater than 4.
Why do counterclockwise angles has positive signs?
Conventionally, angles in the coordinate plane are measured, starting from 0 along the x-axis and increasing in the anti-clockwise direction.
Influence of crossing angle on amplitude in cabling to cabling coupling?
Using the cosine law of illumination, if two cables are laid at right angles, since cos 90 = 0, the coupling will be the lowest possible. If the two cables are laid parallel, the coupling will be maximum. Be aware that shielding or twisting of cable pairs reduces the coupling effect.
What is the function of an u joint in a car?
The u-joint (universal joint) allows the driveshaft to transfer power from the transmission to the differential during constantly changing angles.
Why are cosines positive and negative?
Because the cosine of some angles is positive and the cosine of some other angles is negative.
What are positive and negative angle?
positive and negative angles of 87 degrees
What are negative quadrant angles?
using protactor, we use to draw angles in anticlockwise direction and that angles are called positive quadrant angles. and angles in clockwise direction, these angles are called negative quadrant angles.
Is there a positive or a negative angle?
Yes. Angles may be measured from the direction of the positive horizontal axis and, clockwise is negative, anticlockwise is positive.
What shape has 4 equal angles?
Not sure but I am pretty positive its a square!
Is there any voltage induced in coil when axis of two coils at right angles to each other?
Coils at right angles do not couple if the distance is much greater than the diameters, but at close quarters there might be some small amount of coupling unless symmetry is perfect.
What has no right angles and no equal or parallel sides?
A circle? I'm not too positive on this.
What properties must an object have in order to magnify another object?
positive angles of refraction or diffraction; negative angles of reflection; narrow aberration
What figure has the most obtuse angles?
There is no limit to the number of obtuse angles a figure can have. A regular n-gon has n obtuse angles where n is any positive integer greater than 4.
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.
