Trigonometry (1 Viewer)

[excellence1]

I need help for my assignment in regards to finding an equation about engineering in real life situations. It cannot be right angled trig, it has to be non right angled. It must only be based on 2 unit maths.
Thank you

The magnitude of torque:-

Not too sure about what you mean about being not right-angled.

This assignment is like if HSC maths were like HSC sciences.

Area of a triangle, A= 0.5absinC

 

[InteGrand]

Fourier series.

Fourier series.

too simple for 2u maths

 

[iforgotmyname]

well in physics there is F= BILsin(a) or torque= f x d x sin(a)

the good old scalene triangle

Sorry, I meant worded problems related to trig and engineering and how it's applied in real life situations. Thanks for your help though

OP forget everything else, this is what you need: d = λ/(2n sinθ)

This is the formula for the resolution of electron microscopes, more info
