Question
Solve the equation
a∈/R
Alternative Form
No real solution
Evaluate
1cos(a)−tan(a)+1sin(a)−cot(a)=sin(a)+cos(a)
Divide the terms
cos(a)−tan(a)+1sin(a)−cot(a)=sin(a)+cos(a)
Cancel equal terms on both sides of the expression
−tan(a)+1sin(a)−cot(a)=sin(a)
Divide the terms
−tan(a)+sin(a)−cot(a)=sin(a)
Cancel equal terms on both sides of the expression
−tan(a)−cot(a)=0
Rewrite the expression
−cos(a)sin(a)−sin(a)cos(a)=0
Multiply both sides of the equation by LCD
(−cos(a)sin(a)−sin(a)cos(a))cos(a)sin(a)=0×cos(a)sin(a)
