how to convert sin inverse to cos, tan, sec, cosec x, cot inverse

We often need to convert inverse of sin to either inverse of cos, tan, sec, cosec , cot .In this post we will see how we can do it easily Inverse of sin to inverse of cos Case 1$sin^{-1} x$ and x > 0 Now we can write as $\theta=sin^{-1} x$$sin \theta =x$ Now we

Screw Gauge physics experiment

Introduction

A screw pitch gauge is a precision instrument. It is used for measuring diameter of circular objects mostly wires, with an accuracy of 0.001cm. It consists of a hollow cylinder mounted on a U frame. The hollow cylinder leads to a ratchet which is meant for fine adjustment. The U frame consists of a flat end known as stud and a screw on the other side. This screw can be moved inside the nut by fitted in the U frame by rotating the hollow cylinder called the thimble. This is called the main scale. The hollow cylinder or the thimble is graduated into 50 or 100 equal parts. This is called the circular scale.
