If you also join us at http://www.unicoos.com, it'll be great. #seeyouinclass :-) For 4th year of SECONDARY SCHOOL, we'll solve a MATHEMATICS (or PHYSICS) exercise. In this case, we'll be working on vectors: SUM OF CONCURRENT VECTORS (or FORCES) (F1 and F2) that form a certain angle between them, the so-called RESULTANT FORCE. To do this, we'll apply the formula F=√(F1²+F2²+2.F1.F2cosa), based on the cosine theorem. We'll also solve the sum graphically using the PARALLELOGRAM METHOD, and I'll explain the concept of BALANCING FORCE.
