What basic trigonometric identity would you use to verify that sinx cosx tanx=1-cos^2x

andre [41]

Answer:

$sin^2x+cos^2x=1$ is used to prove the given equation.

Step-by-step explanation:

We have given an equation:

$sinx\cdot cosx\cdot tanx=1-cos^2x$

We will consider right hand side first

tan x can be written as:

$tanx=\frac{sinx}{cosx}$

So, on substituting tan x in the left hand side of the given equation we get:

$sinx\cdot cosx\cdot \frac{sinx}{cosx}$

Cancel common term from denominator and numerator which is cosx we get

$sin^2x$

And we have an identity:

$sin^2x+cos^2x=1$

$\Rightarrow sin^2x=1-cos^2x$

Hence, right hand side is equal to $sin^2x$ .

Find the slope of the line 3,0 and 0,-3

liubo4ka [24]

Answer:

1

Step-by-step explanation:

The slope of the line is 1. To find slope use the formula $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$ , this calculates the change in y over the change in x. So plug in the known values $\frac{0+3}{3-0}$ , this equals 3/3 or 1. This means every time y increases by 1, x will also increase by 1.

Construct a truth table for the logical operator NOR.

Rasek [7]

Answer:

A B A NOR B

F F T

F T F

T F F

T T F

Step-by-step explanation:

The logical operator NOR produces a result that is the negation of the logical operator OR.

The truth table for the logical operator NOR can be obtained by the negation of the results of the truth table for the logical operator OR.

Let A and B be the the logical values (or inputs). The operator OR produces a value of true if and only if at least one operand is true. The truth table for OR is:

A B A OR B

F F F

F T T

T F T

T T T

So, the truth table for NOR is:

A B A NOR B

F F T

F T F

T F F

T T F

Notice that the negation of OR (which is NOR) is obtained by changing the F by T and the T by F in the column of the results.

This table can also be writen with 0 instead of False and 1 instead of True.
