Please someone help me. It's about proving related to transformation of trigonometric ratios. Thank you!!

kvasek [131]

Answer:

see explanation

Step-by-step explanation:

Using sum to product identities

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

cos x + cos y = 2cos( $\frac{x+y}{2}$ )cos( $\frac{x-y}{2}$ )

Note that

sin10° = sin(90 - 10)° = cos80°

Thus

$\frac{2sin(\frac{10+80}{2})sin(\frac{80-10}{2}) }{2cos(\frac{10+80}{2})cos(\frac{80-10}{2}) }$ ← cancel 2 from numerator/ denominator

= $\frac{sin45}{cos45}$ × $\frac{sin35}{cos35}$

= tan45° × tan35° { tan45° = 1 ]

= 1 × tan35°

= tan35° ← as required

The volume of a gas in cubic centimeters v,varies inversely with the pressure of the gas in liters per square centimeters,p when

scoundrel [369]

Answer:

The volume of the gas is $145.45\ cm^{3}$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $y*x=k$ or $y=k/x$

Let

v------> the volume of a gas in cubic centimeters

p-----> the pressure of the gas in liters per square centimeters

$p*v=k$

we have

$v=16\ cm^{3}, p=20\ l/cm^{2}$

substitute and solve for k

$k=16*20=320$

The equation is $p*v=320$

<em>Find the volume of the gas when the pressure is 2.2 L/cm2</em>

For $p=2.2\ l/cm^{2}$ Find the value of v

substitute in the equation

$(2.2)*v=320$

$v=320/2.2=145.45\ cm^{3}$

F(x)=2x/3x^2-3 what is the domain of the function?

konstantin123 [22]

Answer:

Step-by-step explanation:

$f(x) = \frac{2x}{3x^2 - 3} \\\\ Domain: \\ 3x^2 - 3 ≠ 0 \\ 3x^2 ≠ 3 \\ x^2 ≠ 1 \\ x ≠ \pm 1$

D = {x E R/ x ≠ 1 and x ≠ - 1}

I Hope I've helped you.
