Answer:

csc 0

B is correct

Step-by-step explanation:

Given:  Expression, cot 0 sec 0

Simplify the trigonometric expression using identity.

\cot\theta=\dfrac{\cos\theta}{\sin\theta}

\sec\theta=\dfrac{1}{\cos\theta}

\csc\theta=\dfrac{1}{\sin\theta}

\cot 0\cdot \sec 0 \Rightarrow \dfrac{\cos0}{\sin0}\times \dfrac{1}{\cos0}

Cancel like factor from top and bottom

\cot 0\cdot \sec 0 \Rightarrow \dfrac{1}{\sin0}

\cot 0\cdot \sec 0 \Rightarrow \csc 0

Hence, The given expression equivalent to csc 0

Cot 0 is undefinded, sec0=1
A. Sin0=0
B. C<span>sc(0) = 1/sin(0). Since there is no number 1/0, csc(0) is undefined.
C. Cos0=1
D. Cos 0=1</span>

Answer:

A)2

Step-by-step explanation:

we would like to integrate the following definite Integral:

\displaystyle  \int_{0} ^{1} 5x \sqrt{x} dx

use constant integration rule which yields:

\displaystyle  5\int_{0} ^{1} x \sqrt{x} dx

notice that we can rewrite √x using Law of exponent therefore we obtain:

\displaystyle  5\int_{0} ^{1} x \cdot  {x}^{1/2} dx

once again use law of exponent which yields:

\displaystyle  5\int_{0} ^{1}  {x}^{ \frac{3}{2} } dx

use exponent integration rule which yields;

\displaystyle  5 \left( \frac{{x}^{ \frac{3}{2}  + 1  } }{ \frac{3}{2}  + 1} \right)  \bigg|  _{0} ^{1}

simplify which yields:

\displaystyle  2 {x}^{2}  \sqrt{x}   \bigg|  _{0} ^{1}

recall fundamental theorem:

\displaystyle  2 (  {1}^{2}) (\sqrt{1}  ) - 2( {0}^{2} )( \sqrt{0)}

simplify:

\displaystyle  2

hence

our answer is A
