Simplify sin^2y/sec^2 y−1 to a single trigonometric function

liubo4ka [24]

Answer:

$\frac{ { \sin}^{2} y}{ { \sec}^{2}y - 1 } = { \cos }^{2} y$

Step-by-step explanation:

We know that ${ \tan }^{2} y = { \sec }^{2} y - 1$

Also , ${ \tan}^{2} y = \frac{ { \sin }^{2} y}{ { \cos }^{2}y }$

So ,

$\frac{ { \sin }^{2}y }{ { \sec }^{2}y - 1 } = \frac{ { \sin}^{2} y}{ { \tan }^{2} y} = \frac{ { \sin }^{2}y }{ \frac{ { \sin}^{2} y}{ { \cos}^{2}y } } = { \cos }^{2} y$

In triangle RST, angle R is a right angle. If TR = 6 and TS = 8, what is the length of RS

lisabon 2012 [21]

Answer:

RS = 2 $\sqrt{7}$

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

RS² + RT² = TS² , that is

RS² + 6² = 8²

RS² + 36 = 64 ( subtract 36 from both sides )

RS² = 28 ( take the square root of both sides )

RS = $\sqrt{28}$ = $\sqrt{4(7)}$ = 2 $\sqrt{7}$ ≈ 5.3 ( to 1 dec. place )

Solve the equation for y.<br><br> 4.2x−1.4y=2.1

Vlada [557]

Answer:

y=3x- 3/2

Step-by-step explanation:

4.2x−1.4y=2.1

Subtract 4.2x from each side

4.2x-4.2x−1.4y=-4.2x+2.1

-1.4y = -4.2x +2.1

divide each side by -1.4

-1.4y/-1.4y = -4.2x/ -1.4 +2.1/-1.4y

y=3x- 3/2
