How Cross Product Calculator Works?
Vectors are quantities with both magnitude and direction. Vectors help to simultaneously represent different quantities in the same expression.
The standard form of representation of a vector is:
a = a1i^ + a2j^ + a3k^
b = b1i^ + b2j^ + b3k^
Where a1, b1, c1, and a2, b2, c2 are numeric values and i^, j^, k^ are the unit vectors along the x-axis, y-axis, and z-axis respectively.
When two vectors are multiplied with each other and the product is also a vector quantity, then the resultant vector is called the cross product or the vector product. Cross product is represented by a × b. The cross product of two vectors is given by:
Cross product(a × b) = i(a2b3 − a3b2) − j(a1b3 − a3b1) + k(a1b2 − a2b1)
Solved Example on Cross Product:
Find the cross product of two vectors a = 4i + 2j – 5k and b = 3i – 2j + k and verify it using cross product calculator?
Given a = 4i + 2j – 5k and b = 3i – 2j + k
a × b = i(a2b3 − a3b2) − j(a1b3 − a3b1) + k(a1b2 − a2b1)
= i((2 × 1) - (-5) × (-2)) - j((4 × 1 - (5) × (3)) + k((4) × (-2) - (2 × 3))
= i(2 - 10) - j(4 + 15) + k(-8 - 6)
= -8i - 19j - 14k
Therefore, the cross product of two vectors is -8i - 19j - 14k
Similarly, you can use the cross product calculator to find the cross product of two vectors for the following:
- a = 4i + 2j - 5k and b = -1i + 4j - 3k
- a = -2i - 5k and b = -7i + j + k
