Answer:
a ratio is a fraction. For example the ratio 3 pigs to 9 animals can be written as 3:9 which can be written as a fraction; 3/9 which can be simplified by dividing the whole thing by three (Because that is the greatest common factor) and you would get 1/3.
Step-by-step explanation:
We are asked in the problem to evaluate the integral of <span>(cosec^2 x-2005)÷cos^2005 x dx. The function is an example of a complex function with a degree that is greater than one and that uses special rules to integrate the function via the trigonometric functions. For example, we integrate
2005/cos^2005x dx which is equal to 2005 sec^2005 x since sec is the inverse of cos. The integral of this function when n >3 is equal to I=</span><span>∫<span>sec(n−2)</span>xdx+∫tanx<span>sec(n−3)</span>x(secxtanx)dx
Then,
</span><span>∫tanx<span>sec(<span>n−3)</span></span>x(secxtanx)dx=<span><span>tanx<span>sec(<span>n−2)</span></span>x/(</span><span>n−2)</span></span>−<span>1/(<span>n−2)I
we can then integrate the function by substituting n by 3.
On the first term csc^2 2005x / cos^2005 x we can use the trigonometric identity csc^2 x = 1 + cot^2 x to simplify the terms</span></span></span>
Answer:
The scale factor from PQR to P'Q'R' is ½
The equivalent measurement in degrees is 150°
<h3>Measurement of angle</h3>
Angles can be measured in radians or degrees.
Radians are mostly used for very small angular measurement.
Analysis:
For every π radians covered, the angular measurement is 180°
So 5/6π = 5/6 x 180 = 5 x 30 = 150°
In conclusion, the angular measurement in degrees of 5/6π is 180°.
