First off, sin 2 theta = 2 sin theta cos theta. Also, the answer to your question is no. There are multiple double angle formulas, and it is important that you remember them so that you can answer questions correctly.
Remember that -csc^2(x) is a known derivative; it is the derivative of cot(x).
<span>Keeping that in mind, let's put a negative there, and then offset it with another negative, which can conveniently be placed outside of the integral. </span>
<span>(-1) Integral ( -csc^2(x) dx ) </span>
<span>Which evaluates to </span>
<span>(-1) cot(x) + C </span>
<span>-cot(x) + C</span>
Answer:
Annabelle is correct.
Step-by-step explanation:
1. When multiplying two numbers with exponents, the exponents are always added and not multiplied. However, when there is an number with an exponent that has an exponent (for example (5^2)^3) you would multiply them.
2. Applying this to your question would make Annabelle's work correct and Navene's work incorrect.
Hope you understood!
Answer:The last option
Step-by-step explanation:the absolute value bars make it positive but the negative on the outside of those bars make it negative, this -|3|=-3 and -|2|=-2. Furthermore, the double negative on the last two dots make a positive, thus -(-2)=2 and -(-3)=3. With this in mind it is -3,-2,2,3 and -|3|,-|2|,-(-2),-(-3)
Answer:
26.04cm^2
Step-by-step explanation:
28 divided by 20 is 1.4. 1.4 times the area will give you the area of the other figure. 1.4 x 18.6 = 26.04
