2sin+5sin-3cos

It seems like you have an equation with both sine (sin) and cosine (cos) terms. In order to simplify an expression like this, we can use trigonometric identities. First, let's rewrite the expression as: 2sin + 5sin - 3cos Next, we can combine like terms by adding the sin terms together: (2sin + 5sin) - 3cos To simplify further, we can factor out sin: (2 + 5)sin - 3cos This simplifies to: 7sin - 3cos
