Cotxcos2x = 2cotx
cos2x = 2cotx/cotx
cos2x = 2
cos2x = 2cos²x - 1
2cos²x - 1 = 2
2cos²x = 2+1
2cos²x = 3
cos²x = 3/2
√cos²x = plus minus √(3/2)
cosx = plus minus √(3/2)
Answer:
Step-by-step explanation: If 1 pint is equal to 16 oz (1 cup), then 2 pints is equal to 32 oz (2 cups). So, Sarah drank a total of 2 glasses of milk because her glass holds 16 oz, which is a pint. 2 pints is 32 oz which would be 2 glasses of milk.
