# How do you verify the identity tan2theta=2/(cottheta-tantheta)?
Dec 22, 2016
Rewrite $\tan \theta$ and $\cot \theta$ as sines and cosines using color(magenta)(tan theta = sintheta/costheta and cot theta = costheta/sintheta.
$\frac{\sin 2 \theta}{\cos 2 \theta} = \frac{2}{\cos \frac{\theta}{\sin} \theta - \sin \fra... |

7. For a, n > 0 and a ≠ 1; $${{a}^{{{\log }_{a}}n}}=n$$
Proof:
Let $${{\log }_{a}}n=x$$. Then $${{a}^{x}}=n$$.
Therefore, $${{a}^{{{\log }_{a}}n}}=n$$,
Examples:
(1) $${{3}^{{{\log }_{3}}8}}=8$$

# Proof of Sum Rule of Differentiation
The sum rule of differentiation can be derived in differential calculus from first principle. $f{(x)}$ and $g{(x)}$ are two differential functions and the sum of them is written as $f{(x)}+g{(x)}$. The derivative of sum of two functions with respect to $x$ is expressed in mathema... |
# How do you simplify (27^-⅔)/(27^-½)?
May 7, 2016
This is easier than it appears at first, the bases are both 27.
Use one of the first laws of indices. "If you are dividing and the bases are the same, subtract the indices"
Notice that $\frac{2}{3}$ is a bigger fraction than $\frac{1}{2}$
Therefore subtracting in t... |

# If the sum of the coefficients in the expansion of ${\left( {x + y} \right)^n}$ is 4096, find the greatest coefficient in the expansion.
Hint: Sum of coefficients of ${\left( {x + y} \right)^n}$ is obtained when we put $x = y = 1$. And the greatest coefficient is the coefficient of the middle term(s) in it... |
