+280 Im ripping my hair out with these stupid questions. How the heck do i find a cos A and cos B if only have sin A sin B?
From what i have here on my notes from my teacher, it shows different examples. If i had each of one i could do the the problem my just simply plugging it in the formula. So with these ones i tried to find them by doing this. I used this formula
cos ^ 2 = 1 - sin ^ 2 I would just plugin the both of the sin's? I know its wrong now that i need help,
