Determine if the sentence is true based on the text below:
To calculate electric flux you absolutely don't not use magnitude and direction of vectors.

How to calculate electric flux<br>Know the formula for electric flux. [substeps] The electric flux through a surface a is equal to the dot product of the electric field and area vectors e and a. the dot product of two vectors is equal to the product of their respective magnitudes multiplied by the cosine of the angle between them. Determine the magnitude and direction of your electric field vector.
