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.

What is 2 12/13 as a decimal rounded to the nearest tenth
Delicious77 [7]

Here is you're answer:

First, you need to convert the mixed number into a improper fraction, then you have to convert the improper fraction into a decimal, then round to the nearest tenth.

  • 2\frac{12}{13}
  • 2\frac{12}{13} = \frac{38}{13}
  • Now convert into a decimal:
  • 13 \div 38 = 0.34210526315789
  • Find the tenth place value:
  • PV = 8
  • 8 > 5
  • = 0.34210526315780

Therefore you're answer is "0.34210526315780."

Hope this helps!
