The equation is complicated, but thankfully, mathematicians have solved it for some useful cases such as for European options.\nUse the cumulative normal distribution to express the solution to the Black-Scholes equation for the price of options:\n<a href=\"https://www.dummies.com/wp-content/uploads/eqcs0401.gif\"><img loading=\"lazy\" class=\"alignleft wp-image-226715 size-full\" src=\"https://www.dummies.com/wp-content/uploads/eqcs0401.gif\" alt=\"eqcs0401\" width=\"137\" height=\"37\" /></a>\n \n \nThe Black-Scholes solution for the price, C, of a European call option on a non-dividend-paying stock is given by the following formula. The volatility is a lower-case sigma, the risk-free interest rate is r, the expiry time is T, the current time is t, and the underlying stock price is S. The strike price is K.
