What else can I help you with?
When magnitude of vector a plus b is equal to the magnitude of vector a minus b then what is the angle between two vectors a and b?
2pi/3 radian or equivalent 120 degree
If vector c equals vector a plus vector b under what circumstances does c equal a minus b?
When b is zero.
Can the magnitude of a vector have a negative value?
The magnitude of a vector is always treated as non negative and the minus sign indicates the reversal of that vector through an angle of 180 degree.
When does the subtraction of two vector equal zero?
The subtraction of two vectors equals zero when the two vectors are identical in both magnitude and direction. Mathematically, if vector A minus vector B equals the zero vector (A - B = 0), then A must be equal to B. This implies that they point in the same direction and have the same length.
How it can be proved that angle between two straight lines is equal to the angle between their normals?
If two lines have angles theta1 and theta2 relative to some third arbitrary line, then the angle between those two lines is theta1 minus theta2. The normal of a line at a point is a line that is 90 degrees from the line going through that point, so the angle between a line and its normal is 90 degrees. As a result, the angle between the two normals of those lines is (theta1 plus 90) minus (theta2 plus 90), which is the same as theta1 minus theta2 because the two plus 90's cancel each other.
How do you find missing vector if resultant is given?
The Resultant Vector minus the other vector
What is the measure of the third angle of the triangle?
The third angle of a triangle is equal to 180 degrees minus (the sum of the first two angles).
Find the angle which is equal to its own complement?
45o This is because 90 minus 45 is 45.
What does sine minus tan equal zero?
It means that the angle in question is any multiple of 180 degrees.
What measure of A will make this quarallelogram?
To determine the measure of angle A that will make a quadrilateral a parallelogram, you need to ensure that opposite angles are equal. Therefore, if angle A is known, angle C (the opposite angle) must also be equal to angle A. Additionally, the sum of adjacent angles should equal 180 degrees; thus, if angle B is known, angle D must be 180 degrees minus angle B.
If a and b are two vectors and the vector product of vector a and vector b is equal to a minus b then prove that a equals b?
The question is not correct, because the product of any two vectors is just a number, while when you subtract to vectors the result is also a vector. So you can't compare two different things...
How many degrees are in a supplementary angle?
A supplementary angle is a 180-degree angle minus the number of degrees in the given angle.
