Where did that 92.82 and 1.9318P came from?

evaluate the trigo functions and add/subtract like terms

Can you please give an example ?

bakit dinidisregard ung quadrants? hindi ba may negative/postive ung components depende kung saan sila nakapwesto?

Hindi actually yan dinisregard... siniparate lang sa solution ang upward sa downward at yung "to the left" fom "to the right".
