Answer:
[tex] \sin(theta) = \sqrt{ {1 - \cos^{2}(theta)} } [/tex]
Step-by-step explanation:
From trignometery identities , we know that :-
[tex] { \sin^{2}(theta) } + { \cos^{2}(theta) = 1}[/tex]
[tex] = { \sin^{2}(theta) } = 1 - { \cos^{2}(theta) } [/tex]
Here further solving this , we get
[tex] \sin(theta) = \sqrt{ {1 - \cos^{2}(theta)} } [/tex]
