Exercise 1
Compute \(\exp(3-\frac{4}{5})+\frac{\sqrt{3+2^5}}{4-7\cdot \log(10))}\)- Create the vector named
xwhich contains the following values \((10, log(0.2), 6/7, exp(4), sqrt(54), -0.124)\):
- Find the length of
x.R
- R (https://www.r-project.org/) is a free software environment (actually it is a programming language) for statistical computing, data analysis and visualisation (graphics).
- R is an open source project, which means that it depends on a worldwide community of active developers to grow and evolve.
