For the following questions answer them individually
If p and q are statements, then "$$\sim p \Rightarrow p \wedge q$$" is true whenever
For any two statements p, q the statement $$\left(p \Rightarrow q \right) \vee \left(\sim \left(\left(\sim p\right) \Leftrightarrow q \right)\right)$$ is false only when
If A, B, C are subsets of a set X and $$A^1 = X - A$$, then $$\left(A \cup \left(B^1 \cap C^1\right)\right) =$$
A relation R defined on a non-empty set A is called anti-symmetric if
If A and B are two sets such that n(A) = 4 and n(B) = 5, then the number of non-constant functions from A into B is
Two lines $$L_1$$ and $$L_2$$ make intercepts a. —b and b, —a respectively on the x and y axes. Then angle between $$L_1$$ and $$L_2$$ is
Equation of perpendicular bisector of the line segment joining (13, —2) and (-5, 10) is
$$\cos \frac{2 \pi}{6} + \sin \frac{5 \pi}{6} =$$
$$6 \cos \theta - 7 \sin \theta = 0 \Rightarrow (7 \cos 2\theta + 6 \sin 2\theta)^2 =$$
