The correct Answer is:B To find the value of cos36∘, we can follow these steps: Step 1: Find sin18∘ Let x=18∘. We know that 5x=90∘. We can express 5x as 2x+3x. Step 2: Use the sine identity Using the identity sin(90∘−θ)=cos(θ), we have:sin2x=sin(90...

The “Deep State” that so many bloggers love to post long-winded articles about and yak about for hours on podcasts is just another name for the system of super-rich bastards who run our government and profits from them at the expense of the workers—that is, those people who actuallymak...
But with the unit circle definitions of sin and cos, you can see this is equivalent to: tanθ=oppositeadjacent Or, thinking in terms of coordinates: tanθ=yx This explains why tan is undefined for 90° or −270° and 270° or −90° (where x = 0), because you ...
