The primary drivers of the price of an option are the current stock price, intrinsic value, time to expiration or time value, and volatility. The current stock price is fairly straightforward. The movement of the price of the stock up or down has a direct although not equal effect on the...
(25)/7. Rearranging this equation results in sin(A) = sin(25)*12/7. Using a scientific calculator to find sin(25), carrying out the rest of the equation would show that sin(A) = 0.724. To find angle “A,” use the calculator to determine the inverse sine of 0.724. The answer ...
