HELP! NOW! <br> Prove the trig identity:<br> 3sinx/1-cosx=3cscx+3cotx

vichka [17]

Step-by-step explanation:

Given

To Prove

$\dfrac{3\sin x}{1-\cos x}=3\csc x+3\cot x$

Take the Left side of equation and rationalize

$\Rightarrow \dfrac{3\sin x}{1-\cos x}\times \dfrac{1+\cos x}{1+\cos x}\\\\\Rightarrow \dfrac{3\sin (1+\cos x)}{1-\cos^2 x}\\\\\Rightarrow \dfrac{3\sin (1+\cos x)}{\sin^2 x}\\\\\Rightarrow \dfrac{3\sin x}{\sin ^2x}+\dfrac{3\sin x\cos x}{\sin^2 x}\\\\\Rightarrow \dfrac{3}{\sin x}+\dfrac{3\cos x}{\sin x}\\\\\Rightarrow 3\csc x+3\cot x$

Left side is equal to right side

Hence, proved

In a certain chemical, the ratio of zinc to copper is 3 to 16 . A jar of the chemical contains 416 grams of copper. How many gr

Anna71 [15]

Answer:

the number of grams of zinc contain is 78

Step-by-step explanation:

The computation of the number of grams of zinc contain is shown below:

Given that the ratio of zinc to copper is 3:16

And, the jar of the chemical has 416 grams copper

So, the number of zinc grams would be

here we assume the zinc grams be x

Now the equation would be

3 ÷ 16 = x ÷ 416

Now applied the cross multiplication

16x = 416 × 3

x = (416 × 3) ÷ 16

= 78

Therefore the number of grams of zinc contain is 78
