3+2√3 is irrational number |
|
Answer» Assume that 3+2 root 3 is rational.3+2 root 3=a/b(3-a)/b=2 root 3(3b-a)/b=2 root 3(3b-a)/2b=root 3Therefore our assumption is wrong,(3b-a)/2b is a rational number which implies that root 3 is irrational.Therefore,3+2 root 3 is irrational. Let 3+√3 is a rational no. So it is in the form of p/b where q≠0P/b=3+√3=> p/b-3=√3LHS is a rational no, so RHS should be rational,But we know that √3 is irrational. This contradicts to the fact that 3+√3 is rational.Hence 3+√3 is irrational. |

Defination of tangent |
|
Answer» A line which touches the circumference of a circle at only one point The tangent line to a plane curve at a given point is the straight line that "just touches" the curve at that point. Leibniz defined it as the line through a pair of infinitely close points on the curve... The definition of the tangent In terms of the unit circle diagram, the tangent is the length of the vertical line ED tangent to the circle from the point of tangency E to the point D where that tangent line cuts the ray AD forming the angle.
