I'm confused as to how I'm supposed to write the big bracket.


The usage of \left and \right is used to achieve the big brackets.

You could achieve the equation by using the following code:



F = B_{\perp}.I.l \\
\sin{\alpha} = \frac{B_{\perp}}{B} \rightarrow B_{\perp} = B.\sin{\alpha}
F = B.I.l.\sin{\alpha}


The output would look like: enter image description here

    Please write \sin, not just sin. Also, do please remove or comment out the \label directive as the displayed equation doesn't have a number.

  • You may want to add flushright alignement before the closing brace thus it will better stick to @John Doe 's expectation.
