You need to know some of the exact trig values
sin(60) is one of those trig values you’re expected to memorise
when you have the value for sin(60) which you will need to memorise, you need to multiply it by 2 to get the value for x since you rearranged the equation to be in terms of x and there is a 2 in fromt of the sin(60) now
for trig values remember than sin x = cos (90-x)
Are these correct:
What’s the Hand rule😭😭
Learning the triangles is the easiest way ngl
What triangles 😭😭
I was never taught it

Exact Trig Values - Hand Trick | Trigonometry | Maths | FuseSchool
There are some key angles that have exact values in trigonometry. The ones we need to know are 0, 30, 45, 60 and 90.
In this video, we will discover one method to remember what these values are: by counting fingers on our hand!
In the first part we explored a different metho...
