If p+q=p-q then angle between p and q is
If p+q=p-q then angle between p and q is- Let the angle between two vectors P and Q be alpha and their resultant is R So we can write R^2=P^2Q^22PQcosalpha1 When Q is doubled then let the resultant vector be R_1, So we can write R_1^2=P^24Q^24PQcosalpha2 Again by the given condition R_1 is perpendicular to P So 4Q^2=P^2R_1^23 Combining 2 and 3 we get R_1^2=P^2P^2R_1^24PQcosalpha =>2PQcosalpha=P If p and q are statements then here are four compound statements made from them ¬ p , Not p (ie the negation of p ), p ∧ q, p and q, p ∨ q, p or q and p → q, If p then q Example 11 2 If p = "You eat your supper tonight" and q = "You get desert"
