Sec theta - Csc theta / (csc theta)(sec theta)
Sophie [7]

Answer:

sin(x)-cos(x)

Step-by-step explanation:

\frac{\frac{1}{cos(x)} - \frac{1}{sin(x)}  }{\frac{1}{sin(x)} * \frac{1}{cos(x)}  }

Simplify the denominator:

\frac{\frac{1}{cos(x)} - \frac{1}{sin(x)}  }{\frac{1}{cos(x)sin(x)}  }

Simplify the numerator:

\frac{{\frac{2(sin(x)-cos(x))}{sin(2x)} }  }{\frac{1}{sin(x)} * \frac{1}{cos(x)}  }

Divide the fractions: <u>(a/b)/(c/d) = (a * d)/(b * c)</u>:

\frac{(-cos(x)+sin(x))*2cos(x)sin(x)}{sin(2x)}

Use the identity: <u>2cos(x)sin(x) = sin(2x):</u>

\frac{sin(2x)(-cos(x)+sin(x))}{sin(2x)}

Cancel out the common factor (sin(2x)):

-cos(x) + sin(x)

Simplify:

sin(x) - cos(x)

Find the nth term of the sequence:<br>23, 19, 13, 5, -5.......<br>​
Maurinko [17]

Answer:

Step-by-step explanation:

Given the sequence :

23, 19, 13, 5, -5.......

From the sequence, the common difference is unequal, as their is a constant Increment in the difference after successive numbers.

19 - 23 = -4

13 - 19 = -6

5 - 13 = -8

-5 - 5= -10

Hence an constant difference of - 2 after each successive difference.

Hence, this is a quadratic sequence

With the formula

an² + bn + c

Math definitely isn't my greatest subject, if anyone knows how to do this and can explain it to me please help!
Law Incorporation [45]

Answer:

y-1 = 5/3(x-3)

Choice C

Step-by-step explanation:

slope = (y2-y1)/(x2-x1)

(3,1) (6,6)

m = (6-1)/(6-3)

m = (5/3)

the point slope form of a line is given by

y-y1 = m(x-x1)

You have point (3,1)

y-1 = 5/3(x-3)

Choice C
