Please help me I have a test tomorrow
yarga [219]

#5 is very nicely and correctly done.

#7 says: "No matter what X may be, this function of it is always 9 more than 1/2 of X .".

That's a very powerful statement. Now you know that if X is ever 2, the function will be 1/2(2)+9 which is 10.

If X is ever zero, the function will be 1/2(0)+9 which is 9. If X is ever a cow, the function will be 1/2 of a cow, plus the number 9. Which makes no sense, but that's what the function says.

So, when X is -8, the function is 1/2 of -8, plus 9. Which is 5 ... the 'f' of -8.

Whatever X happens to be at the moment, just write that number in place of X in the function, and it'll show you the function of what X is.

f(a bazillion) = 1/2(a bazillion) + 9 .

f(a-28) = 1/2(a-28) + 9 (but simplify it)

How do you express sin x + cos x in terms of sine only?
frez [133]

Answer:

\sin x + \sqrt{1-\sin^2x}

Step-by-step explanation:

Given: sin x + cos x

To change the given trigonometry expression in term of sine only.

Trigonometry identity:-

  • \sin^2x+\cos^2x=1
  • \cos x=\sqrt{1-\sin^2x}

Expression: \sin x+\cos x

We get rid of cos x from expression and write as sine form.

Expression: \sin x + \sqrt{1-\sin^2x}        \because \cos x=\sqrt{1-\sin^2x}

Hence, The final expression is only sine function.
