What basic trigonometric identity would you use to verify that sin^2x +cos^2x/cos x = sec x

gogolik [260]

Answer:

The basic identity used is $\bold{\sin ^{2} x+\cos ^{2} x=1}$ .

Solution:

In this problem some of the basic trigonometric identities are used to prove the given expression.

Let’s first take the LHS:

$\Rightarrow \frac{\sin ^{2} x+\cos ^{2} x}{\cos x}$

Step one:

The sum of squares of Sine and Cosine is 1 which is:

$\sin ^{2} x+\cos ^{2} x=1$

On substituting the above identity in the given expression, we get,

$\Rightarrow \frac{\sin ^{2} x+\cos ^{2} x}{\cos x}=\frac{1}{\cos x} \rightarrow(1)$

Step two:

The reciprocal of cosine is secant which is:

$\cos x=\frac{1}{\sec x}$

On substituting the above identity in equation (1), we get,

$\Rightarrow \frac{\sin ^{2} x+\cos ^{2} x}{\cos x}=\sec x$

Thus, RHS is obtained.

Using the identity $\sin ^{2} x+\cos ^{2} x=1$ , the given expression is verified.

Savanna is playing a game with her friends. She tells them to each pick a number, and then she directs them to: 1. Multiply thei

Kaylis [27]

Answer:

x = - 6

Step-by-step explanation:

Let x b number, according to instructions´ we must

1.-Multiply by 4

2.-Subtract 6

3.-Divide by 2

4.-Arturo says his new number - 15

4,.Which one was the original number ??

The maths expression for that is :

(4*x - 6 ) / 2 = - 15

we solve for x

4x - 6 = - 30

4x = - 24

x = - 6

Plz plz plz I need 546463+54543 times 64 it’s due in 4 min

Airida [17]

Woah! Those are some big numbers! Anyways heres my answer: I used the old school way of fuigreing this out but using the pencil and paper I fuigred out 546463+54543 is equal to 601006 and if you were to multiply this by 64 (it took a LONG time for me and quite a few mess ups) its 38464384. Though I gave you the answer I'm just wondering if you could use a calculator because it would be a whole lot easier if you were able to do so.

Is |4x+2|+6=0 no solution, all real numbers, 0, and 2

algol [13]

|4x + 2| + 6 = 0

Subtract 6 from each side: |4x + 2| = -6

But the absolute value of a number is always positive.
No value of 'x' can ever make |4x + 2| negative.

So the equation has no solution.
