Question

If 5cosx=6sinx Find tanx​

Answer 1

Answer:

Step 1: 4 sin(x) + 5 cos(x) = 0

Step 2: Rearrange this so that you get 4 sin(x) = - 5 cos(x)

Step 3: Think back to the formula. Divide both sides by cos(x) to get 4 tan(x) = -5

Step 4: We have the value of 4 tan(x), but we want tan(x). So what do we do? Correct again - divide both sides by 4 to get tan(x) = -5/4, or tan(x) = -1.25, in decimals.

Hooray! But we're not done here. Another good practice is to take the answer and substitute it back into the original equation, to check that both sides of the equation are equal with this value of tan(x). If it is...
